An ICE restart doesn't completely blow away the ICE state; the existing ICE candidate pair continues to be used while the ICE restart is going on. So I think it would make more sense logically, and be simpler, for ICE restarts to not create new `RTCIceTransport` objects.

But there's also a question of what happens when a new DTLS association is formed. We could say that when a remote description is applied that indicates a new DTLS association, you get a new `RTCDtlsTransport` object. But if we do that, we really need some way of informing the application. I'd be  fine with just saying "the DTLS transport is like the ICE transport; multiple DTLS associations are conceptually handled by a single DTLS transport object". I think that's what people have assumed until now.
