I don't plan on doing it.  I hate conditionals, wish they would die, and
suggest we should move to all modules instead.  The kernel policy server
isn't built in a way to make support in conditionals easy.  I can do it
if we have to (it's software, we can do anything), but I don't want to
continue to encourage conditionals.
