This is looking good.  Thank you for driving this forward.

I think it is crucial to make the "localhost" abstraction be usable without
concerns
(but with caveats and guide-rails as proposed in the doc).  Otherwise we'll
be stuck eternally with people using "http://127.0.0.1/"; URLs and will need
to special-case that when we want to retire IPv4 off of hosts.

It might make sense to collect some statistics on how often "localhost"
is looked up on various recursive resolvers to determine how big of a
problem
it will be for them to "NXDOMAIN".
