IPF was almost removed a while back, but got a reprieve at the last 
minute.  Personally, I'd rather have a system where the firewalls were 
modular and did not have to be in the base.  Then we could have only one 
in base, which would probably be IPFW, and others could be installed 
from ports.  (Yes, this is non-trivial.)
