(A common rationale is that they want to use their IPR to bring convergence and interoperability to the industry).  Let’s hypothesize that this happens, now or in future, from Company X, for some IPR in the WebRTC specifications.

I'm having trouble following the logic here. What technology are you 
imagining that Company X will put IPR claims on, and what conformance do 
you imagine that it would require?

(We could also consider the case of someone, call it Company G, claiming 
IPR on some non-codec part of WebRTC technology and refusing to license 
it at all. We can discuss the relative chances of the two things happening.)

If Company G does its thing, both 1 and 2 risk a ruinous lawsuit from 
Company G.

My impression from the meeting was that the people speaking in favour of 
the proposed solution had evaluated the risks, and were ready to make a 
decision based on their evaluation.

YMMV.
