The type of response you send back has a impact.

For a "mail" a secure NXDOMAIN response saying that "mail." doesn't exist
should be fine.

For "foo.home" you actually want a insecure response with a insecure
referal or at least you want "DS home" to come back as a secure
NODATA rather than a secure NXDOMAIN.  This assumes we want to
formalise the defacto use of .home for names in the home.

"corp" would be similar to "home" technically.  The arguments for
formalising ".corp" would be different as most corporations already
have namespace in the global DNS from which they can make their own
private namespace delegation whereas most homes don't.
