Correct, I forgot to mention that the PR yet does not address the ufrag
issue, waiting for a WG consensus.

Note that there is currently a discussion in RTCWEB on whether a ufrag
change should trigger an ICE restart. But, as an ICE restart does not
automatically trigger a DTLS restart I assume it won’t affect
draft-dtls-sdp. Worth keeping in mind, though.

I will submit a new version.
