I think that when the user asks for ipv6 explicitly, they should get
back ipv6 (or get nothing/a failure).  If the user has specified the
protocol, it's presumably because they really want that protocol.

If they don't specify the protocol version, they get back either/both
ipv6/ipv4 now (depending on the system), don't they?
