Given how unreliable embedded subtitles tend to be in desktop media
players (at least in my experience) I think it's very likely someone
than hoping that the embedded subtitles can be reliably detected in all
different combinations of media frameworks and browsers. I guess
standardizing on an embedded caption/subtitle format might be possible
after we actually have decided on baseline codecs though...

Indeed, I expect that some would even abuse the id parameter to pass the
caption text directly, although that isn't very elegant.
