This is crazy talk.  We have absolutely no idea what will or will
not end up being run from the home.  Whether people will need to
lookup information about the home when it is unreachable or not.
How do you debug if you can reach home or not if you can't get the
addresses of the machines at home?

The DNS was designed with the idea that there would be redundent
servers.  It is not designed to deal with not being able to connect
to any servers for a zone and it really does not work well when
this is the case.
