Yes, but I don't think there is an inherent conflict. RFC 2373 specifies the behavior on the wire i.e. what is carried in IPv6 packets. Implementations might do various things at the API interface, but the an implementation should ensure and :: doesn't appear as the destination in the IPv6 packets it sends. > When '::' is the destination address: > - some use the first available interface's address > - some use the loopback address > > Is there a chance that one of these will become the acceptable norm?

This was done to be consistent with the IPv4 Solaris code. Unfortunately the introduction of the mechanism in the IPv4 Solaris code was before my time. I don't think it existed in BSD 4.3tahoe but I haven't checked.
