Re: [webrtc-pc] No normative definition for "Determine if negotiation is needed to transmit withTrack in place of the sender's existing track" in replaceTrack

I believe that the renegotiation determination is implementation specific, yes.   As an example, the sender's existing track is  `null`, it is desired to replace it with a non-null track, but encoding resources are not available.
