Three suggestions:

1. Drop "within 30 days." Let ARIN staff determine the appropriate
hold time for returned addresses, both for recovered legacy and
non-legacy addresses. Staff are bright and highly competent; they
won't unreasonably sit on addresses while there's a waiting list and

2. Specify that "No such space shall be designated for return to
IANA," solving ARIN staff's issue.

3. Specify that while this policy is in effect, ARIN shall neither
request nor accept IPv4 addresses allocations from IANA under global
policy 2009-3.

Why do #3? As written, this policy proposal obstructs other regions
from ratifying and using global policy 2009-3. In theory, they could
decide they're more generous than we are,  return addresses and allow
their redistribution to areas with need. But they can't do that while
we hover ready to gobble and hold those addresses without giving
anything back.

Realistically there's no chance the other regions would return
addresses to IANA for the same reasons we won't. But this isn't about
reality, it's about politics. Call the bluff. We want to make sure
ARIN isn't "the reason" they can't ratify and use 2009-3 themselves.

Besides, it's only fair. If we won't contribute, we shouldn't take either.
