I think at this point it is up to the chairs to decide. Just please keep in
mind that updating ice-sip-sdp and sctp-sdp to be inline with what JSEP is
proposing would be difficult since this will cause backward
compatibility issues with RFC 5245 outside of RTCWEB.

Also, proposed change raises a new issue, which is what values should be
set in c= and m= lines when protocol in m= line does not match the default
candidate.
