	Probably because there are "better" packet filters that could just
	"drop in" and choosing one over another would probably cause
	endless bickering that we don't need. My personal bias is toward
	the ip_filter package from down under and I'm sure there are
	others. I'd rather not have to rip out some other filtering
	code in order to use the one I want and I'm sure others would
	feel the same about their religeous packet filter/logging choice...
