You don't need to see the prefix for 10/8 to be able to pass packets through hosts in said prefix. Some consider it poor form to use RFC1918 space for hosts that are visible to the outside world. As long as you don't _announce_ said space to the rest of the world it really only breaks MTU path discovery and maked debugging a little more difficult.
