This is a legitimate worry, but it's based on incorrect information.

Stub resolvers already sink localhost queries themselves - they don't rely
on their recursive servers.

Recursive servers frequently do not implement the localhost requirement in
RFC 6761 - for example, BIND does not.

So in practice this draft is only a small tweak to current practice.
