It already removes UP status from interface, so there is action which 
could be tracked by devd. No need to destroy interface if it was not 
created by you. But from other side devd is more complicated and 
system-wide case that some trivial custom shell script, so I would 
prefer to use it just for something common, like running dhclient with 
adding something like ifconfig_tap1="DHCP" to rc.conf alike to normal 
Ethernets.
