Am not trying to assess blame. `goog-remb` is described by webrtcHacks (https://webrtchacks.com/wp-content/themes/parament/custom-pages/sdp/68.html) as

however, Firefox 69 includes `goog-remb` in the SDP of Mozilla WebRTC implementation (http://lists.w3.org/Archives/Public/public-webrtc-logs/2019Jun/0105.html)

> Chromium  `a=rtcp-fb:102 goog-remb`
> Firefox `a=rtcp-fb:120 goog-remb`

The various concerns can sort out the blame, if any, for extending SPD beyond a given specification. 

Firefox still non-standard `mozCaptureStream()`. 

Am asking _how_ the feature is intended to work.
