This avoids getting into an inconsistent state of the request (assert),
and it also allows some real-life cases to succeed without using
a forbidden address in any way (even though they *are* weird).

I can still imagine weird setups where a request gets failed even
though it would be resolvable without *using* a forbidden address,
but none of these seem reasonable anyway (or common in practice).

Some people might want the rebinding module generally but still use
policy to allow local addresses in some specific cases.
