on other designs, you need at least multiplex 2 to make sure your point defense fires after your weapons (or the other way around).

Is this something new? For me, PD has always fired irrespective of multi-plex. In fact I often have PD equipped ships before I have any multi-plex and they take out the missles just fine while the beam weapons take out the ships. The only possible exception could be PD firing at satellites. This may restrict the direct fire weapons to firing at the satellites too.... but I don't think so.
