I've been pondering whether this is going to work right with resolution changes. Does Chrome let you record a remote track that changes resolution? AFAIK Firefox doesn't allow recording of remote tracks period.

I also did this [demo page](https://jan-ivar.github.io/dummy/replace-track.html) where I remove a stream's video track and add a different video track on the same event loop (the API alternative I mentioned). This causes `UnknownError` from MediaRecorder in Firefox. In Chrome there's no error, but I don't see a recording (maybe autoplay restrictions interfering?) cc @Pehrsons 

Just wanted to share what I'd tried.
