So far I haven't seen such feedback from any implementor. I've only seen me
and Maciej speak up on this and we've both said that implementation-wise
this is similar to exposing an accessibility tree for the contents of
<canvas> elements. Certainly not trivial, but doable and something that
needs to be solved in order to make canvas accessible (which I hope we
agree should be a MUST level requirement).

However I could easily have missed other implementor feedback. If that's
the case a SHOULD level requirement might be ok. But I'd be curious to hear
how that implementor was planning on dealing with canvas.
