Do you:
1) Not believe in PMTU-D
2) Not believe in filtering RFC1918 sourced traffic at enterprise boundaries
(of which an exchange would be a boundary)
3) Not believe packet-passing devices have legitimate needs in contacting
hosts, even if hosts don't have legitimate needs for contacting them? (a
superset of 1, above)
4) All or some of the above?

I would love if RFC1918 were adhered to such that L3 packet-passing devices
either weren't numbered out of those blocks, or allowed what juniper allows
with the ability to select the ip address with which packets sourced by
the L3 packet-passing device sent traffic (other than primary ip on
destination interface). The latter would permit intra-enterprise use
of RFC1918 addresses, while still conforming with RFC1918. Failing that,
use of RFC1918 addresses in places where inter-provider packets get
RFC1918 sources, is a violation of RFC1918.

In any event, exchanges are inter-enterprise, and shouldn't be RFC1918.
