[arin-ppml] ARIN-prop-127: Shared Transition Space for IPv4Address Extension

Just a note that I am going to run various things up the flagpole as I
think this through and come to a final conclusion and the below was one
of those things. I realize it is pretty moot after *complete* runout as
a new provider won't be able to get any IP addresses but a new provider
also has the leeway to tell someone "don't use 10/8 for your internal
addressing, we are going to use that for NAT for you".
In fact, I have a link to one provider right now that is in 10/8 space
