I'd rather not have to treat the last policy as "special" and stop it from 
being purged / pruned...

So I would rather change the .rng and deal with a system that has no policies 
(easy, do nothing if there is nothing to do). You can not add zones to such a 
system as there is no policy to add it to; so I can't see any bad things 
happening... It is also a simpler change (one character as opposed to I don't 
know how many lines).
