My instinct says that this is beyond what could reasonably be added for 1.0.

It seems to me that it's information that could be exposed via the
RTPSender / RTPReceiver interface (which I can't find the drafts for at
the moment), it doesn't seem to map well to a concept that's generic
enough to be right for incorporating into the MediaStreamTrack model.

Could you try to create a specific suggestion based on the RTPReceiver
proposal?
