ipfilter(4) needs maintainer

I do not stand in any good stead to comment on this, but I have used
IPFilter more extensively than PF when it comes to FreeBSD and packet
manipulations. As a user, what I can say is this:

1. The only firewall that seems 'native' to FreeBSD is ipfw and I believe
it works very well for some users who are able to adapt to it's syntax.
2. PF is being felt to be part of FreeBSD, but it too lags far behind
OpenBSD implementation - almost like it's unmaintained. There has been
debates about this which were never concluded. Most of you will agree with
me on this.

 IPFilter is obviously NOT going to make it in 10.x and never releases
because of those changes which have led to this thread/debate.

So my take is there is a very simple answer/solution to this debate, which
conforms to the K.I.S.S principle:

3. There is NO need to look for a maintainer. Simply DEPRECATE IPFilter
from 10.x and put out a BIG Notice/Billboard somewhere where whoever needs
to run FreeBSD because of IPFilter will find it. I doubt there is such a
person anywhere because there are firewall implementations out there that
can address this. Just put it out somewhere that IPFilter is NOT AVAILABLE
on FreeBSD 10.x upwards and go ahead and remove it from the system. Nobody
will complain. If anyone does, tell them that IPFilter is supported on
FreeBSD upto 8.x (or is it 9.x? On my 9.x systems I use PF).

4. It's pretty easy for a newcomer to adopt and adapt to a firewall that is
properly supported. Newcomers don't have much choice anyway. They decide to
go with a system after finding out that it "meets their requirements".

Let's remember that there are other Unix variants out there with Firewall
implementations too.

I hope this helps you big boys settle this debate.
