Comment (by bugzilla):
In general, localhost is a TLD, and it must be resolved through DNS. In
one of related tickets stated that 127.0.0.1 can be seamlessly redirected
to public IP by the system. DNS can return "not found". So, there are
enough reasons to stop rely on localhost as a security solution.
General practice is that services listen on 0 (0.0.0.0 and/or [::]).
Address filtering is a task of firewall. To handle all tasks by tor
instance is not a good practice.
