If the existence of an m-line implies that an RtpSender already exists
for it, addTrack creating a new RTPsender would imply that you either
replace the old one or that you end up with two RtpSenders referencing
the same m-line.

Since the latter is breaking the model we just proposed, I assume that
you mean the former - but why?
