LSR not withstanding, anyone directly connected to you can devise
their own routing via static routes. Anyone on your own network
doesn't need to (assuming their defaulted.) rfc1918 is merely an illusion.
If you're taking care of the "inside", you've already added the security
which rfc1918 isn't providing. This is the point that I believe many others
are trying to make. Security through obscurity is no security at all.
