> The basic idea of Wayland is that it is a simplification and streamlining of a display server protocol. The work of designing that core protocol is already done and doesn't need to be done again, the original developer likely did it because they found it interesting or useful to work on in some way.
The mere existence of Wayland does not justify removing X11. I'm not trying to say that the X.org and fd.o developers shouldn't do as they please; I'm saying that I'll keep X11 until I see a compelling reason to drop it for Wayland.

I'll have to take your word for it, since I have literally never seen this happen (been using Linux as my daily driver since 2006 and have used dozens of WMs and all the major DEs). I agree that something inconsequential like the visual appearance of widgets or some such might not be consistent with the overall WM or DE theme, but X11 programs in general can run on a bare X server.
The only kind of non-trivial breakage I could imagine happening is accessibility features malfunctioning due to the absence of a particular DE, but I don't know to what extent this is the DE's fault, the program's fault, or the toolkit's fault.
