Actually, I believe that this circumstance is the reason that the immediate needs clause
exists.

4.2.1.6. Immediate need
If an ISP has an immediate need for address space, and can provide justification to show that the address space will be utilized within 30 days of the request, ARIN may issue a block of address space, not larger than a /16 nor smaller than ARIN's customary minimum allocation, to that organization. These cases are exceptional.

Perhaps, in practice, since it is located in principles (not sure how or why that occurred), and there isn't anything concrete stating that it should be treated as an exception to 4.2.4.1, it does not get implemented as I believe was intended. Staff would have to clarify that. If that is the case, it would be a relatively simple proposal to fix:

Amend section 4.2.4 by adding:
	4.2.4.5 Exceptional Cases of Immediate Need
		If a subscriber member has a customer who needs a larger block than remains in the subscriber member's
		free pool, then a request under section 4.2.1.6 shall apply as an exception to the requirements in 4.2.4.1.

I really think that removing the needs test is unlikely to gain consensus, even at the smaller point. There is clear resistance in the community to this idea and I expect that opposition will remain strong.

If people support the idea above, I'm happy to put it into a policy template and get it started in the process. If there is strong support, it can probably be moved through the process fairly quickly.
