Re: [rtcweb] Use case change request: Identity in multiuser calls

OK! Then I think we have the same view. Will you work on the wording, or should we start with the current one?

This makes sense. I just want it to be explicit.
It's relevant for the discussion EKR brought up about "who do I
authorize when I say OK to using a camera" - if it's the far end of the
connection or the service I'm connecting to.

In the centralized server case, with the added text, it's definitely the
service, and I'd like to keep it that way. So this is text added in
order to make sure we don't generate a requirement....
