Never coded, made a change or updated X11. It always just works. But reading this thread that spawned some of the feelings around the ‘fragile’ codebase sounds like it is really hard to work on
From what I've seen he hasn't actually addressed any bugs or features in xorg... ever. I'm not sure if that even grants the title of "maintainer". Shuffling code around is fun and easy, but not necessarily productive.
a) noone looks at the code
b) they make random user-facing changes
c) random churn that makes the code better (preferably with as few user-facing modifications as possible)
IMO the best option is c). Guy is literally doing the single best thing possible.
