A long-ago proposal - that was never really dismissed - gives a site the ability to call the constructor of AudioMediaStreamTrack and VideoMediaStreamTrack, and all that getUserMedia does is connect those tracks to active sources. In fact, this proposal was an important part of the settings proposal that was accepted, but it was a little controversial for reasons that I'm not to clear on. It solves a number of problems, though it doesn't always help with respect to generating SDP (and it could, with a naive browser implementation, increase the passive fingerprinting surface, but no worse than the OfferToReceiveAudio or OfferToReceiveVideo constraints already do the same).
