I agree with Rich, but I also think we've yet to see a compelling case
for exposing AT make and model info.

While it's true that several ATs have been notorious for bugs associable
with particular versions, I'm not sure this historic fact points to a
requirement going forward.

Haven't these bugs been related to the AT performing its own HTML
parsing--at least from an IndieUI reachable perspective? If I'm not
wrong about that, I submit there is likely to be little, or at least
much less of this going forward.

there's much better a11y support in today's browsers and parsing engines
obviating the need for this kind of solution.

In other words, I suspect the historic pressure relates to ATs that were
also serving as browsers, something that I submit is going away. Am I
wrong?
