That's may be true for PeerConnection, though it doesn't have to be,
depending on how we intend to resolve certain media path issues.  My
expectation for gUM was that the output would be stable from a track
perspective at least.  But you are right, it's probably unworkable.
My vain hope was to confine that sort of dynamism to processing-type
