Actually, that's a good thing. This makes it trivial to detect which peers
aren't doing egress filtering. If people just filtered RFC 1918 space,
everything would just look better, but the underlying problem wouldn't be
solved: it would still be possible to launch very hard to trace or stop
denial of service attacks from those networks.
