Hi! I would really love to give our AD a revised version of this I-D soon.

I didn’t do an exhaustive search, but I did note that
RFCs 8825, 8827, and 8834 refer to the the W3C specification normatively as follows:
https://www.w3.org/TR/webrtc/
There is no chance that there is any energy whatsoever to go back and change those three to refer to a specific version. So I think we will need to call those done.

For this I-D, I originally submitted the following PR to update the reference to the final recommendation.  I have updated that PR to also move the reference to be normative. See:

https://github.com/rtcweb-wg/jsep/pull/1024

Is there any objection to moving the reference to normative?

Harald or Cullen can one of you comment on this? The vast majority of PRs merged into the 202110126 version were marked as editorial.
