   I don't recall who, but someone pointed out that <canvas> is no less
semantic than <img>, since it's essentially a dynamic <img> element with
improved fallback.

   Interesting! So Microsoft isn't necessarily saying that <canvas> is
out of scope, so much as the 2D Context API.

   I think it would be more productive to standardize the 2D Context the
way it is currently implemented, then allow a separate group to develop
a second-generation API. There are already too many applications
dependent on current cross-browser implementations.
