The idea is not to route it in the first place. Besides, it probably
already exists on some RBLs.

Packet filtering is what routers are for, and a BGP bogon feed does
indeed make it very simple, as you can route to null0 all the bogons. I
do this already operationally, I can discard that traffic even before
the firewall.
