Ugh, I thought I'd killed that off.  I'm solidly in the camp of people
who think the autoloading is a mistake.  If you're going to hardcode a
list of module you want to load, /boot/loader.conf is the place, not
this indirect hack that bites people on the ass because it works for
real interfaces, but not all sorts of other types due to the
impossibilty of generalizing support.  For extra fun, making a typo on
your ifconfig command line can lead to loading a random module.

That's probably a good solution for ipv6_network_interfaces.
