The only point I am trying to make is that while there is absolutely
nothing in using address space as defined in RFC-1918 that will break
PMTU-D, using 1918 addresses for public router interfaces which send
packets to public networks (in this case, the Internet) from that address
is outside the scope of what 1918 permits and can break things when
combined with other entirely legitimate and correct practices.

As a result, it is unwise to encourage people to use 1918 addresses in
such an inappropriate way.

Since everyone agrees on this, hopefully this thread can now rest.
