In recent time I think there has been one proposal dealing with 
rejection [1]. There was one comment on rejection [2] (incidentally 
given by me) basically saying "your proposal looks good, but not sure we 
need this now".

So based on recent discussion this does not seem like something a lot of 
people want. And, I guess there are always the options of signaling 
(outside the SDP) to the sender to switch off video, or munging the SDP.
