That's fascinating information, thanks for taking the time to collect it.

Hmm. What I really want to say is this: people are asking for "canvas
accessibility", but they should really be asking for "application
accessibility", and sometimes the right way to make a canvas-using
application accessible to some users does not involve canvas (see your
examples...). Therefore we should not add accessibility APIs to canvas for
situations where a non-canvas alternative is preferred.

It strikes me that based on your examples, what we really need to make many
canvas applications accessible is not canvas APIs, but better audio APIs!
Which we are working on, fortunately :-).
