Here's what the text actually says:

"5.1 Returned Legacy Addresses

Legacy IPv4 addresses returned to or recovered by ARIN will be made
available for registration and distribution in the ARIN region within
thirty days of their receipt."

There's no argument here that once an address is added to ARIN's
inventory it's a done deal. The proposal doesn't seek to do otherwise
nor does the language imply that it would.

All that this proposal does is codify the instruction to return these
addresses to ARIN inventory and use them. The current situation is
ambiguous and open to interpretation. This has nothing to do with the
IANA at all. In fact, in the absence of a global policy, this simply
makes the instruction "use the addresses".

With regards to accepting legacy addresses from entities "only" in the
ARIN region, I think that's a fair point and will put it on the list
of final modifications.
