I stand corrected. Marty had the right of it: you're denying the facts
on the ground.

It's not unreasonable to write policy which changes those facts but if
the changes are to be clear, they must reference the facts as they are
both before and after the change. The facts today are: there IS such a
thing as legacy addresses and they're presently immune to most
ARIN-region policy. Moreover, that policy rarely says so explicitly.
Hence policy which should impact legacy addresses will be more clearly
understood if it explicitly says so.
