Wonderful news. This is a big step to filling one the gaps in the various waylands that prevented them from being taken seriously (none of the waylands were really ADA compliant before since they lacked any screenreader possibilities). I hope every wayland compositor choses to implement these two protocols in mutually compatible ways.

As someone with progressive retinal tearing I'd been really worried the last 5 years or so with everything switching to one of the waylands and there being no accessibility. This is a relief. It'll probably get there before I go functionally blind.
