Then, what is required is the creation of (cloned) interfaces to
be seperated from assigning them addresses.  But even that is
insufficient because pf.conf allows "interface:network" etc wich
expands to the networks on an interface.  Unlike ipfw which walks
the ifnet structure to compare addresses, if at the time of firewall
configuration, the interface has no address, then the rule will
expand to have no address.

I put it to you that users of pf know that it starts with default
allow and changing this will result in a POLA violation.
