I would also like to know the answer. It *seems* to envision a path along those lines, but I trust that at minimum there would not be a W3C Recommendation before such work has been published.

No, they do not. Nomensa, Deque and TPG spring to mind. I think it is also fair to say that companies like IBM, HP, Microsoft, Apple and Google have done a lot of important work to ensure the rights of people with disabilities can be exercised in practice - even while it is fair to acknowledge that they have a patchy record.

Against which technical experts who are passionate advocates for accessibility who have carefully assessed the technology over years have declared that there isn't a problem.

I suspect the truth is somewhere in the middle, but I cetainly don't recognise your claims as unarguably factual.

That seems to misrepresent the situation.
