This "retain backwards compatibility stuff" can be taken too far
backwards. I think ipfilter first can out with NO ipv6 support, then
ipv6 was added using 2 rule files, and later yet it was redesigned to
use a single rules file. Talking about way back around RELEASE 4.0. Now
ipfilter does not work with 2 rules files for a very long time. It's now
time to clean up the old ipv6 only stuff so the documentation and
/etc/rc.d/ipfilter boot script reflects how it works today. And another
thing to point out is the ipfilter source code has been forked and is
now under Freebsd maintainership.
