Re: [webrtc-pc] The prose around "simulcast envelope" falsely implies that simulcast encodings can never be removed (#2723)

Re-reading Section 5.4.1, I agree that there is an issue. While the section seems to imply that the simulcast envelope is established by `addTransceiver()` alone, this is not correct, if only because the answer can reject layers/RIDs.  My inclination is that the envelope is only really determined once the initial negotiation has completed.  However, this does raise the question of whether `setParameters()` can modify parameters originally set by `addTransceiver()` prior to completion of the initial negotiation.
