Re: [webrtc-extensions] Peer Connection and back/forward cache (#200)

Does Safari have data on how well this works in practice on video conferencing webpages?

It seems to me the main gain here is the roughly 5.35% ([5.65](https://chromestatus.com/metrics/feature/timeline/popularity/3452) - [0.3](https://chromestatus.com/metrics/feature/timeline/popularity/3451)) of webpages that only use WebRTC for fingerprinting. E.g. only blocking BFCache after sRD could have a large impact without disrupting video conferencing.

Websites can already do that, so I think that is orthogonal (thanks to persisted permissions or even permission grace periods). We messed up gUM which doesn't require transient activation, but it's probably too late to change that. UAs might be able to mitigate this with muting — idea in https://github.com/w3c/mediacapture-extensions/issues/39#issuecomment-955131893).
