Not impossible to maintain, just no one cares to anymore. It’s not new and flashy, which is all people care to work on these days. So they make something new with half of what the old standard did. For the rest, they let it fall to others to write hack workarounds, because hey, they didn’t need features x y and z, not their problem, right? Why should they care if they create a new standard that breaks shit for tons of people, it does what they want… which is likely fricking useless things like games. This obsession with gaming is out of control, and it’s pulling devs away from the things that really need working on. Get a gosh darn console if you need to drown your sorrows in games, ffs. Meanwhile, fix X11, or replace it, but do so FULLY so you don’t break things that have worked for over a decade.
