After we've had this behavior for as long as we have, I doubt we can
safely change it.
I do agree it is unintuitive, and it also disagrees with ipv4 as you
already know.
There are several crucial areas where our behavior deviates between
ipv4 and ipv6, including this case. And as more people start making
real use of ipv6 we will see these complaints pop up over and over
again from users.
