The two concepts have different lifetimes; a track can be created before 
a PeerConnection.

I like to support the model of "you are sending a track over a 
PeerConnection; it appears the same on the other side" as much as 
possible. Having an ID on the track is part of that model.

 From my perspective, MID is part of the adaptations we do in order to 
make SDP work for us.
Having rules from SDP spill over into the track model seems like 
tail-wags-dog to me.
