I think that one of the desirable properties of WHIP is that it can easily
be implemented with minimal changes to the WebRTC stack -- in the current
draft, the only place where you need to delve into the internals of the
WebRTC stack is to generate and parse the somewhat baroque RFC 8840 syntax
for trickled ICE candidates.

My undetstanding of Nils' point is that while ICE keepalives are the
natural thing to do in the server->client direction, if your stack is
doing ICE consent instead, then it's fine to keep using that.  Does anyone
see a problem with that?
