Just to make it sure, if you mean "accepting IPv4 packets on an
AF_INET6 socket as IPv4-mapped IPv6 addresses" by "the model in
2553", Solaris does not follow the model, AFAIK.  Also, NetBSD disable
the model by default.

...however, those corrections do not affect the main stream of this
discussion.  We've fully, fully discussed this (in the apifolks list),
and have seen so many different views, and, as a consequence, could
not reach consensus on a single unified behavior.  Sad to say this,
but I don't think we'll be able to force vendors a particular behavior
based on a particular view of the model, like "the correct thing is to
deprecate IPv4-mapped IPv6 addresses"...

So, IMHO, the only feasible thing we can do now is to accept the
differences of various implementations, and make a guidance of how to
deal with the differences with a minimum effort.
