This makes it possible to have DNS requests for certain domains routed differently than normal requests, which is for instance useful when using policy routing to route traffic over a VPN but DNS requests for the VPN endpoint itself, should be routed differently. It doesn't make much sense to configure a firewall mark at the level of a network interface, but at the level of a DNS delegate it can be very useful.
