As I understand, blind people can't use wayland right now.

I know some blind people who tolerate it but yeah, I find it completely unusable at the moment. I haven't tried Gnome recently but last time I tried it I had apps like Bitwarden malfunctioning in some very, very weird ways that just... Never happened on Xorg. If I remember right, it was things like forms not being read properly or something, can't remember off the top of my head now. But it certainly didn't leave me with a good impression; it made me think this Wayland thing was just half-baked. Also, Orca modifiers were passed-through directly to the compositor and Orca wasn't allowed to intercept them either, which made just using my computer feel awkward since I'd always need to remember to turn off caps lock every time I wanted to do something even remotely complicated. I've heard that Gnome has solved this but as I said above, I think this may be a Gnome (and at most KDE) thing, and not something that everybody has decided to just do.
