This PR needs more work to incorporate additonal findings: 1. Its restriction that `encodings[0].rid` must match the first rid in a=simulcast seems too strict, when implementations [allow rid pruning not just from the tail](https://github.com/w3c/webrtc-pc/issues/2762#issuecomment-1264036923) 2. While letting remote offers prune rids is required by JSEP, browsers' immediate exposure of this effect on `encodings` in`"have-remote-offer"` seems poorly executed as [it cannot be rolled back, and effects stack over back-to-back SRDs](https://github.com/w3c/webrtc-pc/issues/2762#issuecomment-1271875081). Instead, waiting until local answer to prune `encodings` avoids both problems (no `encodings` to rollback and no stacking). Such waiting would maintain invariants the spec offers today, which seems more conservative as a first PR here, while moving us closer to how browsers work. I think that's the right place to stop, as whether we should go any further I think requires further WG discussion. -- GitHub Notification of comment by jan-ivar Please view or discuss this issue at https://github.com/w3c/webrtc-pc/pull/2758#issuecomment-1276924713 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
