Absolutely. The question is: is that enough? I hope it is.

Basically the RtpSender is given a MediaStreamTrack ad the app can already
request some constraints for that track (assuming video) such as frame rate
and resolution. Having that and also `temporalLayers` and `spatialLayers`
for generating layers of less quality is good enough IMHO.
