Nothing is bulkier because of ipf or any other non-pf filter, since you 
will get it only if you specified it in your config, and it isn't the 

We really shouldn't argue from some simplifying black and white "new == 
good, old == bad" standpoint here.

Apparently Joris has his reasons to use ipf and we have to see if pf (or 
ipfw2) cuts it for his setup. Likewise, others are still using ipfw2 for 
one technical reason or the other. See what Matt pointed out, for one, 
and I've also heard that it's faster (from other people).

I'm not saying we must keep ipf (and I'd rather say not), but the 
decision whether to keep it or nuke it should not be made based upon its 
age (at least as long as it works, which apparently it does), but rather 
upon whether pf is suitable for these scenarios instead.
