To avoid fragmentation, ISPs are encouraged to require their customers to return address space if they change ISPs. Therefore, if a customer moves to another service provider or otherwise terminates a contract with an ISP, it is recommended that the customer return the network addresses to the ISP and renumber into the new provider’s address space. The original ISP should allow sufficient time for the renumbering process to be completed before requiring the address space to be returned.

So, I'm not sure a policy change is actually required, as there is noting ARIN can do about address leases absent connectivity when they are made as reassignments.

Well, there is still section 12.

That would require consensus by the community for something like this proposal.

An issue for a future proposal, if so.
