Handing out larger blocks to the same number of LIRs shouldn't have any higher cost to ARIN. If we define all allocations at nibble boundaries, then the fees should be done similarly:

This would definitely be a concern. As it is, a medium in IPv4 can 
easily find themselves as a Large in v6. What gets me is why an XX-Large 
was added.

The policy change handled that, allowing for a renumber.
