Sure, I can understand people working on software X for a long time getting fed up with it and start working on software W.

I can also understand that these people have strong opinions on why W is so much better. The only trouble is that others, who are possibly not developers of window systems, may not care, or may find that it breaks their software, or may not want to write software that depends on W and doesn't work on X.

So what if Xorg is "barely maintained"? It works. Hell, as long as it works, it's likely better for it not to change. If there are issues, in the free software world we say "patches welcome". No developer should feel chained to a project.
