I can see the argument for dualstack -- we shouldn't remove v6 addresses
if we're talking to the server over v4 and conversely. I suspect the
multi-homed use-case is a bit less important, right?

Is there a corresponding IPA ticket or some link to a freeipa-users
thread?

Please note I agree with the technical requirement, but there's limited
time, so we should prioritize.
