This is what IP_FREEBIND is for, which is why it needs to be supported by
the socket activation configuration.  It's been considered best practice
for some time for IPv6 services binding to particular configured IP
addresses to use IP_FREEBIND because IPv6 network setup can take an
unpredictable amount of time.
