We're being very explicit that this isn't intended to blow up the WG like
comment 22 does.  It's merely adding two methods to PeerConnection that
allows JS apps to optionally avoid the issues of adding many media streams
to SDP.  We're focusing on making the smallest change that can bring the
biggest value, not rewriting all of WebRTC from scratch.
