Usually I manage to keep the Strangelove hand in check and not feed
the troll, but the matter was raised (at least in the ARIN region).

I believe that the arguments that shared transition space were IETF's
purview were compelling.  I'm no fan of non-globally-unique space in
general, but forcing the RFC route was the least-worst route for
things to move forward.

Randy, I trust that you're also vigorously advocating people's use of
UK-MOD-19850128 (aka net 25) as "just more 1918 space" inside their
organizations too?  After all, it's what I encourage *my* competitors to do.
