Necessary, but not sufficient.  Unfortunately, the definition of a
"session", while sufficient for the description in 7022, is not quite
precise enough for this use case.  The implication there is that it
means "RTP session", which is both not at the right level of
granularity, and not directly actionable.

I also note this little gem:

   A longer-term persistent RTCP CNAME is sometimes useful to facilitate
   third-party monitoring, consistent with [RFC3550].
