I closed #2779 because introducing more state requiring rollback seemed unwise when [no browser supports rolling it back](https://jsfiddle.net/jib1/kjn2deLm/18/). It also violated the [original intent](https://github.com/w3c/webrtc-pc/pull/2081/files) which seemed to be for sRD(offer) to establish initial simulcast envelopes [in time for ontrack](https://github.com/w3c/webrtc-pc/issues/2014#issuecomment-432874655), but trim encodings only in answers (which cannot be rolled back). This and the spec's ban on _"[remotely initiated RID renegotiation](https://w3c.github.io/webrtc-pc/#set-description)"_ prevent `sender.getParameters().encodings.length` from decreasing in have-remote-offer (or increasing from their rollback). One way to lift our ban on _"[remotely initiated RID renegotiation](https://w3c.github.io/webrtc-pc/#set-description)"_ (to comply with JSEP O/A) without giving up these invariants would be: once envelopes have been established, defer trimming them until the answer. -- GitHub Notification of comment by jan-ivar Please view or discuss this issue at https://github.com/w3c/webrtc-pc/issues/2762#issuecomment-1271875081 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
