Yes, but "serve it locally" is just one way, and it has its own
registry, which is not the case with the other ways. And it is
inconsistent: the semantics of ".localhost" in RFC 6761 are "serve it
locally" but it is not in the registry of locally-served zones.

I'm glad I don't maintain a DNS resolver, it seems messy to just get a
comprehensive list of domains that a resolver has to know by default,
with the rules to follow.
