Your belief is fine with me - you haven't seen the prototype running on
Safari ;-)

This is a non-compelling analogy that I already discussed on the list -
IMHO it's simply a matter of taste whether to proliferate HTML elements
or extend the API of an existing element a bit. For what it's worth,
people _could_ have extended "img" instead of going for "canvas" ...

My use cases are neutral to the finer points you raise here - I would
simply do a pause() before setting start/end to new values and calling
play() again. If necessary, there could be restrictions in the spec on
resetting those values during playback, or no guarantees of audible
glitches from the UA. Either way is fine, just not dropping start/end
