Right, it doesn't. For example, a lot of DSL providers configure their
equipment to not return ICMP host unreachable on an unused IP address.

Dropping unwanted packages instead of rejecting them makes sense for
brain-dead applications like emule/edonkey which don't care anyway,
but it doesn't give you any security gain. Facing a "no security gain"
situation, you can as well be a good neighbor and honor the RFCs.
