ICE-lite entities don't even perform connectivity checks. Requiring they perform consent freshness doesn't seem to make sense to me (of course, we can come up with a new spec ICE-lite-with-consent, but that's a different problem).

I am not saying you can't spoof a public VoIP service to send RTP anywhere. Legacy ICE entities perform connectivity checks today and not consent and consent freshness. Do we want to make them more secure? Sure. It however is a problem of different scope and need to be solved in MMUSIC or elsewhere, IMHO.

draft-ietf-rtcweb-stun-consent-freshness is about making the WebRTC browser more secure. It however allows an RTP endpoint (that also does ICE) to use the mechanism to make it more secure or compute RTT or carry network information or whatever. However, requiring every RTP endpoint perform it seems asking too much.

My take:
WebRTC browser - MUST
WebRTC devide - SHOULD
Other RTP entities (including WebRTC gateway) - MAY

Thoughts?

That's the logical conclusion, yes.
