Interesting, though I would not remove it.  It should be marked as
depricated and the /etc/rc.d/ipfilter shell script updated to emit
a warning that it is depricated, but it should still be processed
to retain backwards compatibility and NOT lock someone out of a
system who has just done an upgrade to a newer version.
