This is the kind of initiative I’d prefer to see from X preservationists. Great job, I hope it succeeds. I prefer Wayland, but there’s still a place in the world for X; it just needs new dev teams to shoulder the burden.
I disagree. The choices in the Linux ecosystem lead to unnecessary fragmentation and development/packaging nightmares. I say let X11 die, bury it, and never let it rise again. Then we can all focus on making just one display server as good as possible.
You cannot possibly use this as an argument in Wayland's favor. X11 sucked because it baked everything, including multiple outdated kitchen sinks, into a single Xorg monolith. Wayland sucks because it factors out everything, including really important features, into optional extensions, ensuring that anything more interesting than "draw pixels to a window" will always be different on every single compositor.
