The JSEP spec specifies m-line recycling:

 o  If any MediaStreamTracks have been added, and there exist m=
      sections of the appropriate media type with no associated
      MediaStreamTracks (i.e. as described in the preceding paragraph),
      those m= sections MUST be recycled by adding the new
      MediaStreamTrack to the m= section.  This is done by adding the
      necessary "a=msid", "a=ssrc", and "a=ssrc-group" lines to the
      recycled m= section, and removing the "a=recvonly" attribute.

Based on the minutes from IETF 89, we were going to take this to mmusic.
