Many comments on this thread are about the pros and cons of leaking the local IP in an ICE candidate entry. You can certainly discuss this, but in my understanding, that's not what this post is about at all.

The issue is about leaking the local IP in the foundation which is supposed to be some sort of opaque UUID - the local IP isn't supported to be in there at all, whether you want LAN connections or not.

Is this correct?

Foundation was designed to be a tie breaker. If multiple candidates are valid with the same type you could use the lower foundation.

Foundation is specified in ICE RFC. Almost two decades before mDNS candidates were discussed! I doubt privacy of IPs was ever a consideration
