What makes you think that it would treat packets arriving on the WAN interface any differently?
I'll gladly learn about the topic more. In my opinion the home router is a default gateway for the LAN so it is reasonable for it to accept on the LAN interface(s) any packets with source IP from LAN network. For any packets with LAN IP source and non-LAN-IP destination it should forward them to the WAN interface (while NAT-ing the source address). However there is no reason no accept any packet on WAN side that does not have destination address matching WAN IP. Just like there is no reason to accept and process packets with non-LAN IP source coming to LAN ports. Or accept and process packets with source or destination IP from private IP space coming to WAN interface.
