I'm probably picking a particularly silly example of an address famliy
here, but do you suppose we should duplicate the whole processing
again the day IPv8 comes out to interpret /etc/mygate8 and
$defaultroute8?

For `simple' (i.e. host) setups, the default route is supposedly
picked up from Router Advertisements.  For router setups, the need to
manually configure non-link-local interface addresses, set up Router
Advertisement, etc., makes the `simplification' provided by such a
mechanism seem fairly negligible.  Actually I believe it's making the
issue more complicated: you have to edit one additional configuration
file besides ifconfig.if and rtadvd.conf, which is either
/etc/mygate6 or /etc/rc.conf.
