I'm not super familiar with what transitioning to CR entails, but can you
say something about what goals you have for interoperability, in both the
"implementations pass the same tests" and "two implementations can
communicate" sense) sense?

In my work to bring Blink's Web IDL files closer into alignment with the
specs that we link to, I'm mostly looking for non-standard things that need
attention, but I also notice things that are in specs but not in Blink.

On RTCPeerConnection, there's at least currentLocalDescription,
pendingLocalDescription, currentRemoteDescription, pendingRemoteDescription
and canTrickleIceCandidates. There are also things from partial interfaces
that are harder to spot, like the sctp attribute. Some of these are not in
Gecko either.

Would it be helpful to the WG with a list of things that seem to
implemented in <2 browsers, or what criteria are you using?

Regarding test coverage,
https://github.com/w3c/web-platform-tests/tree/master/webrtc is fairly
limited and improving automated testing seems blocked on things like
https://github.com/w3c/web-platform-tests/issues/5563. Automation aside,
how will you determine the coverage, i.e. how do you make sure that the
sctp attribute is tested and that a lack of implementations would show up
as test failures?
