I also find the existing behaviour useful with VPN links, which go down
and come back up with the same IP address when I move my laptop from one
location to another.

It might be nice if "ifconfig ${interface} [down|destroy]" or "ifconfig
${interface} ${family} ${address} delete" had an extra flag to mean
"also invalidate any sockets bound to this address, or to any address on
this interface".
