"nohost" gathering policy

[aboba]

ORTC has an RTCIceGatherPolicy of "nohost" while WebRTC 1.0 does not define an RTCIceTransportPolicy of "nohost":

There are use-cases where I am not interested in the local candidates such as when talking to an SFU. In that case, the SFU will discover the candidates as peer-reflexive.
Would ICE be faster in this case if the local agent did not have to create pairs and do checks? I think that is marginal at best.

So the nohost option would only be useful if the user agent would place more privacy restrictions on gathering candidates such as a prompt asking for permission. I haven't seen that yet and the "only default route" gathering policy (mode 3 from https://tools.ietf.org/html/draft-ietf-rtcweb-ip-handling-03) seems to work well enough.

Away with it ;-)
