The core of the proposal was to get rid of implicit cloning and make the 
API more intuitive. For example, addTrack() would really add the 
argument track instead of creating a clone under the hood.

The ability to add the same track instance to several media streams is 
merely a consequence of the API changes; not the design itself. I don't 
feel that strongly about it.
