When ICE restart is not in progress, "UDP/TLS/RTP/SAVPF" proto MUST be used if default (only) candidate is a UDP candidate and "TCP/TLS/RTP/SAVPF" proto MUST be used if default (only) candidate is TCP candidate.

I don’t see any real befits to implementations to this change and I don’t think the rtcweb consensus was around the currently solution. Do you see some advantage to implementations to this?
