Is it really the assumption of Hixie? In 
http://lists.w3.org/Archives/Public/public-html/2011Mar/0436.html, Hixie 
gave as example:

<video src="movie.vid#track=Video&amp;track=English" autoplay controls 
mediagroup=movie></video>

which is a media fragment URI that selects 2 tracks.

I don't see the conflict yet. Media Fragment URI spec allows to select 
multiple tracks as this was a clear requirement so there is no reason to 
change this.
