The "once every three months" restriction would be useful in preventing
I don't see that the "an organization may not receive a smaller block
than their documented need" is going to have much practical effect.
ARIN has not had a practice of asking organizations to demonstrate that
their actual need is not actually greater than what they've attempted
to justify, and I doubt ARIN would start doing that. So the effect of
the "may not receive a smaller block" clause is going to be that
organizations are going to find the largest block they can on the
transfer market, and then go to ARIN with justification for that size
(or smaller, if they can't justify the whole block), and then transfer
it. Someone who can justify a /15 will have no trouble justifying a
/16, and ARIN isn't likely (at least not absent specific policy) to
attempt to determine that the organization could really justify a /15.
So all that really changes if thay provision is added is organizations
have to negotiate the transfer before going to ARIN with the
justification. This obviously creates a risk that the justification
will not be accepted, or that the seller will find another buyer before
ARIN completes its review of the request (possible mitigated by the
buyer paying a portion of the sales price to get the seller to hold
it). And the buyer would have to accept the risk of successfully
justifying a certain amount of space and then having the transfer fail
for some reason, at which point he'd be stuck with that size and not be
able to find a smaller block to transfer.
Overall, that would seem to inject a lot of risk into the process, for
very little gain in actual efficiency.
