[whatwg] Quality Values for Media Source Elements

Wasn't there talk of adding a @media attribute to <video> which could,
among other things, hold bitrate information which would allow the UA
to auto-determine whether it should play a file?

This would require a change to the current selection algorithm, as the
UA now has to make a 'best guess' of which file to use rather than
just choosing the first which works, but it's probably worth it.
(Plus the other benefits of @media, such as declaring that a
particular source has subtitles burned in, etc.)
