OK cool. Then the only problem is this:

> For each MediaStream that was associated with the transceiver when it was created via addTrack or addTransceiver, an "a=msid" line, as specified in [I-D.ietf-mmusic-msid], Section 2. If a MediaStreamTrack is attached to the transceiver's RtpSender, the "a=msid" lines MUST use that track's ID. If no MediaStreamTrack is attached, a valid ID MUST be generated, in the same way that the implementation generates IDs for local tracks.

There is no clause for what if the track's ID is already in used by another transceiver (due to replaceTrack or addTransceiver). In that case we must generate an ID too.
