Take node that tipical wish publishers are going to be tools like ffmpeg or
OBS,  I doubt they will provide the flexibility you are looking for.

I dont mind labeling the content of the different tracks as per the sdp
attribute, but I would be against renegotiation/dinamically adding removing
tracks.

Anyway, as said before, this case could be implemented by assigning one url
to each stream (which could be even send from different devices) and
managed at service level.
