I think there is danger is saying "never routable" (I am not trying to
change your words, just adding emphasis) as opposed to "not guarenteed
routeable". I do not yet think (see below though) we need another class of
address, but others may disagree.

Thinking more about this, and going off the IPv6 track for a moment, if we
do have a specific /8 (in IPv4 terms) that can be added to the bogon lists
and shared amongst the RIRs as 'unrouted PI', this could be used for
'enterprise interconnections'. Like anything, it would of course be a scarce
resource, but the filter lists would not grow by much more than a /8. Might
be some mileage in it after all...
