I agree. I also believe that SMIL is addressing a level and degree
of functionality more than HTML should. A SMIL file should be a
value source for <video> or <audio>, but the whole question of media
*integration* ('play this in parallel with that in these two regions,
and then play this other in a third region') should be deferred to
SVG integrated parts of SMIL and there has been some criticism that
the integration made some odd corners. This might have been
necessary in SVG, I'd rather not go there but maintain a clean
layering, which we can do in this case.
