Comment (by yawning):

 I guess if the address portion actually resolves to something using the
 system resolver (`getaddrinfo`) it'll be accepted, but the same thing goes
 for torrc as well (ADD_ONION and torrc based HSes both use common code to
 handle parsing/validating this stuff).

 I still can't reproduce success when it shouldn't.... :/
