I think those are good points.
With respect to touch controls, we are in a rare situation where what's good
for one type of disability is bad for another (and visa versa). A device
with 100% virtual controls is great for a person who can't use their hands
(assuming some form of alternate input is supported), but bad for people who
can't see...
We need to find wording that helps both groups.
