Accessibility is broken on Wayland because accessibility is an afterthought in Linux spaces and very few people are willing to make the internal backend changes needed to fix Orca.
I personally use x11 for a different reason: my preferred desktop is MATE, and the wayland port is not yet in the debian repository.
When forky comes out, I might switch.
x11 has been a hegemonic technology since the 19 fucking 80s.
its hegemony has not been entirely broken as of yet, and wayland isn't up to speed with x11 on everything.
x11 will likely always have a niche somewhere in the world, long after it has been superseded.
