I'm not sure if I understand you, can't you set the transport protocol
on the peer in the mr3.8.1? The only difference between two releases,
from my point of view is that in mr3.8.1 you have one preference instead
of two (rtcp_feedback has been combined with rtp transcoding).

We kind of do this already, because if callee is on the websocket we
default to UDP/TLS/RTP/SAVPF.
