How would that work?  The description in rc.conf(5) does not make it
appear that it supports the sort of thing I'm after.

Here's the functionality I'm talking about, in the form of a patch to
3.0's /etc/rc.d/network, network,v  (I may have details such
as the eval line wrong; this is an untested adaptation of the patch I
use with 1.4T.)  What should I put in /etc/rc.conf.d/network to get
such functionality?  It's not obvious to me in the least.
