I'm all for being fuzzy. We have to: we don't know the application, so we can't dictate what the application should do.

This is just as true for #t=10,20 as for #xywh, by the way. Our suggestion of highlighting the part of the timeline that's relevant only holds for applications that have such a timeline, and which allow user interaction in the first place.

I think we have to say something like "using a fragment id on an html document usually does it in this way. Unless you have a good reason to do it differently we suggest you follow the same principles for media fragments".
