Ok... that makes sense,  thank you.

I would expect ARIN to refuse the transaction in that case.
4.6.1 does say   rather clearly  about   aggregation and returns :
should only be accepted under this policy if they are in the interests of
the community"

Clearly any transaction that could be at any risk of impairing ARIN's
ability to allocate addresses in the near future, would not be in the
interests of the community.  ARIN should choose to decline in that case,
 or continue to work with the holder of address resources,  to select an
alternative not  requiring ARIN allocate too large of a block.

If the blocks are already short prefixes, or will be too short a prefix,
then the aggregation benefit can be outweighed..

Also,  renumbering such a large block should be very painful for an ISP:  I
am not sure, under what circumstances  a request such as that would
actually be likely.
