>Isn’t it a bit late to do something like this tied to X?
At the moment, Wayland is used only by a minority of users, and most are still on X11. Sure, distros may often default to Wayland, yet almost no distro has switched the user's default upon upgrading.
Most users aren't new users or installing on new systems, and even for new users X is occasionally still default (e.g. every existing BSD, some KDE distros).
I estimate it's another 5 years before another new computer cycle and Wayland maturing will make X less relevant. 15-25-more years before we could even consider removing support.
