Some people believe the earth is flat, so that issue is undecided?

RFC1918 addresses are not "free addresses" they are private-use ONLY
addresses which must not appear in public networking space. It cannot be
made much clearer than that. Science has spoken. RFC1918 addresses on
public interfaces are bad. Doesn't matter who disagrees with it or how
convenient it is to adopt. There is consensus on this issue.

Exactly why they should be expunged from ISP backbones. What if an ICMP-DU
message had to go the other way, from ISP space out to the Internet?
