Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.
Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating everyone else (e.g., people using just an X11 window manager or something like GNUstep) in the process.
As 2024 is winding down:
For the record, even in the latest Raspberry Pi OS you still can't drag a file from inside a zip file onto the desktop for it to be extracted. So drag-and-drop is still broken for me.
And Qt move() on a window still doesn't work like it does on all other desktop platforms (and the Wayland folks think that is good).
And global menus still don't work (outside of not universally implemented things like qt_extended_surface set_generic_property).
The Wayland project seems to operate like they were starting a greenfield project, whereas at the same time they try to position Wayland as "the X11 successor", which would clearly require a lot of thought about not breaking, or at least providing a smooth upgrade path for, existing software.
In fact, it is merely an incompatible alternative, and not even one that has (nor wants to have) feature parity (missing features). And unlike X11 (the X Window System), Wayland protocol designers actively avoid the concept of "windows" (making up incomprehensible words like "xdg_toplevel" instead).
DO NOT USE A WAYLAND SESSION! Let Wayland not destroy everything and then have other people fix the damage it caused. Or force more Red Hat/Gnome components (glib, Portals, Pipewire) on everyone!
Please add more examples to the list.
Wayland seems to be made by people who do not care for existing software. They assume everyone is happy to either rewrite everything or to just use Gnome on Linux (rather than, say, twm with ROX Filer on NetBSD).
Edit: When I wrote the above, I didn't really realize what Wayland even was, I just noticed that some distributions (like Fedora) started pushing it onto me and things didn't work properly there. Today I realize that you can't "install Wayland", because unlike Xorg, there is not one "Wayland display server" but actually every desktop envrironment has its own. And maybe "the Wayland folks" don't "only care about Gnome", but then, any fix that is done in Gnome's Wayland implementation isn't automatically going to benefit all users of Wayland-based software, and possibly isn't even the implementation "the Wayland folks" would necessarily recommend.
Edit 12/2023: If something wants to replace X11 for desktop computers (such as professional Unix workstations), then it better support all needed features (and key concepts, like windows) for that use case. That people also have displays on their fridge doesn't matter the least bit in that context of discussion. Let's propose the missing Wayland protocols for full X11 feature parity.
Edit 08/2024: "Does Wayland becoming the defacto standard display server for Linux serve to marginalize BSD?" https://fossforce.com/2024/07/the-unintended-consequences-linuxs-wayland-adoption-will-have-on-bsd/
- A crash in the window manager takes down all running applications
You cannot run applications as root- You cannot do a lot of things that you can do in Xorg by design
- There is not one
/usr/bin/waylanddisplay server application that is desktop environment agnostic and is used by everyone (unlike with Xorg) - It offloads a lot of work to each and every window manager. As a result, the same basic features get implemented differently in different window managers, with different behaviors and bugs - so what works on desktop environment A does not necessarily work in desktop environment B (e.g., often you hear that something "works in Wayland", even though it only really works on Gnome and KDE, not in all Wayland implementations). This summarizes it very well: https://gitlab.freedesktop.org/wayland/wayland/-/issues/233
Apparently the Wayland project doesn't even want to be "X.org 2.0", and doesn't want to provide a commonly used implementation of a compositor that could be used by everyone: https://gitlab.freedesktop.org/wayland/wayland/-/issues/233. Yet this would imho be required if they want to make it into a worthwile "successor" that would have any chance of ever fixing the many Wayland issues at the core.

As of February 2024, screen recording is still broken utterly on Wayland with the vast majority of tools. Proof
Workaround: Find a Wayland compositor that supports the wlr-screencopy-unstable-v1 protocol and use wf-recorder -a. The default compositor in Raspberry Pi OS (Wayfire) does, but the default compositor in Ubuntu doesn't. (That's the worst part of Wayland: Unlike with Xorg, it always depends on the particular Wayand compositor what works and what is broken. Is there even one that supports everything?)

Apparently Wayland relies on nouveau drivers for NVidia hardware. The nouveau driver has been giving unsatisfactory performance since its inception. Even clicking on the application starter icon in Gnome results in a stuttery animation. Only the proprietary NVidia driver results in full performance.

Update 2024: The situation might slowly be improving. It remains to be seen whether this will work well also for all existing old Nvidia hardware (that works well in Xorg).

One of the arguments seems to be that CSD is a must on Wayland. " ... "I’m burnt from it and are not interested in it any more.") Server-side window decorations are what make the title bar and buttons of all windows on a system consistent. They are a must have_ for a consistent system, so that applications written e.g., Gtk will not look entirely alien on e.g., a Qt based desktop, and to enforce that developers cannot place random controls into window titles where they do not belong. Client-side decorations, on the other hand, are destroying uniformity and consistency, put additional burden on application and toolkit developers, and allow e.g., GNOME developers to put random controls (that do not belong there) into window titles (like buttons), hence making it more difficult to achieve a uniform look and feel for all applications regardless of the toolkit being used.
Red Hat employee Matthias Clasen ("I work at the Red Hat Desktop team... I am actually a manager there... the people who do the actual work work for me") expicitly stated "Client-side everything" as a principle, even though the protocol doesn't enforce it: "Fonts, Rendering, Nested Windows, Decorations.

Apparently Wayland (at least as implemented in KWin) does not respect EWMH protocols, and breaks other command line tools like wmctrl, xrandr, xprop, etc. Please see the discussion below for details.
- Screen recording and casting
- Querying of the mouse position, keyboard LED state, active window position or name, moving windows (xdotool, wmctrl)
- Global shortcuts
- System tray
- Input Method support/editor (IME)
- Graphical settings management (i.e. tools like xranrd)
- Fast user switching/multiple graphical sessions
- Session configuration including but not limited to 1) input devices 2) monitors configuration including refresh rate / resolution / scaling / rotation and power saving 3) global shortcuts
- HDR/deep color support
- VRR (variable refresh rate)
- Disabling input devices (xinput alternative)
As it currently stands minor WMs and DEs do not even intend to support Wayland given the sheer complexity of writing all the code required to support the above features. You do not expect JWM, TWM, XDM or even IceWM developers to implement all the featured outlined in ^1.

X11 atoms can be used to store information on windows. For example, a file manager might store the path that the window represents in an X11 atom, so that it (and other applications) can know for which paths there are open file manager windows. Wayland is not compatible to X11 atoms, resulting in all software that relies on them to be broken until specifically ported to Wayland (which, in the case of legacy software, may well be never).
Possible workaround (to be verified): Use the (Qt proprietary?) Extended Surface Wayland protocol casually mentioned in https://blog.broulik.de/2016/10/global-menus-returning/ "which allows you to set (and read?) arbitrary properties on a window". Is it the set_generic_property from https://github.com/qt/qtwayland/blob/dev/src/extensions/surface-extension.xml?
Games are developed for X11. And if you run a game on Wayland, performance is subpar due to things like forced vsync. Only recently, some Wayland implementations (like KDE KWin) let you disable that.
(Details to be added; apparently no 1:1 drop-in replacement available?)
xkill (which I use on a regular basis) does not work with Wayland applications.
What is the equivalent for Wayland applications?
Is it true that Wayland also breaks screensavers? https://www.jwz.org/blog/2023/09/wayland-and-screen-savers/
Other platforms (Windows, Mac, other destop environments) can set the window position on the screen, so all cross-platform toolkits and applications expect to do the same on Wayland, but Wayland can't (doesn't want to) do it.

I disagree. Arguments about the ideology or motivation behind software are arguments about software.
Nah. Because this is a discussion of display protocols, where anal references are for children and trolls.
Also totally off topic, even though not as off topic as your ruminations about your ass in the context of display servers. I suggest you take your quest of linguistic liberation to the lexicographers.
