@ibc i am not assuming it is useless, i am trying to understand it's uses. i read that it uniquely identifies an rtp stream, and hence might be replaceable by rid + mid. i did not read about it being used to synchronize to different rtp streams to sync audio and video. if that is the use case for it, and there is no alternative (ex. as what @alvestrand  suggested in blink-dev), then we will need it.
We will also need to understand if it can be signaled without ssrc, otherwise we need more spec work as well.
regarding capabilities of clients, i think this is where contributors (me included) need to work to have implementations fully spec-compliant. and if cname is optional, we should work to support that.
