Yes; the reason -b [::1] works is because InetAddress.getByName("[::1]")
works. It's not a case of the AS exerting effort to allow it to work;
we'd have to add code to make it not work.
I'd say that we should allow [] but not recommend it.
Agreed. If the AS stops supporting it we will break people who for
whatever reason have needlessly added the []. If we do that we need to
have a good explanation (almost a FAQ) as to why we made that choice.
For tools, it's a question of parsing the IP address
(getAddressByName
should do it), determining if it's a nameless IPv6 address, and if so,
escaping it; not too onerous a burden in my opinion.

URL port (+ password) delimiter is the same as IPv6 IP's group delimiter - in this
case [] are needed in _every_ case, but again - only when we are using _literal_ IPv6
address, not name. In an URL brackets are important to use because ambiguity can be
occurred very easily.

-bmanagement=IPv6 because it is really bad and at least unprofessional... in every case
we'd like to specify literal IP address, we should do this _only_ without bracket,
because this is only one possible text representation...
