IMO iptables isn't so great that one would actually want to do this. The entire ruleset needs to be one continous area in memory, so it can not be changed, only replaced. To make it useable over pfkey would mean many things that are currently done by iptables in userspace need to be done in the kernel. There are multiple other reasons, but I don't think its even worth discussing this. This of course doesn't mean I'm against reducing the number of different classification engines.
