That was made clear in the message about which list to discuss things on and the proper venue for discussion.

How is this even possible at this point? The "W3C API" simply punts the whole actual "API" to the IETF for standardization.

Text like this in the spec: "The createOffer method generates a blob of SDP that contains a RFC 3264 offer with the supported configurations for the session, including descriptions of the local MediaStreams attached to this RTCPeerConnection, the codec/RTP/RTCP options supported by this implementation, and any candidates that have been gathered by the ICE Agent" are ridiculously underspecified, given that "a RTC3264 offer" can be almost anything that meets its syntax requirements, and yet the space of valid offers is clearly much smaller than this.

So either 1) "this WG is the right place" to specify the entire API, in which case we really should get on that or 2) "the IETF WG is the right place" to specify pretty much all that matters, in which case the W3C WG is pretty much held hostage to a process that doesn't appear to be converging, especially now that people have realized that any time you want to extend SDP you need to A) go see the MMUSIC WG and B) make sure it won't break any of the SIP applications that use SDP.

Who is "we" in this case? Clearly not the application developers who have spoken up recently. Nor at least one of the major browser vendors.

That sounds like a fun exercise. I don't see how it advances the goal of getting a W3C specification that others can implement in an interoperable way.
