This is an idea based on past operation right here at ARIN.

Right after CIDR was started, there was a move, although not mandatory to 
get those requesting more IPv4 space, especially those holding many 
multiple blocks to give these parties a larger single block, and time to 
renumber into the larger block before taking back the multiple smaller 
blocks for reassignment to others with less need.

I know with IPv6 that some amount of space is being held in reserve so 
this idea would not be triggered until at least one expansion request was 
received by ARIN.  I remember that early ISP assignments were a /35, and 
they were permitted to expand into a /32 if they wished.  I do not know if 
this wiped out the reserve space or not.

Does anyone know how much space is currently being held in reserve when a 
new /32 assignment for an ISP of IPv6 space is being made at ARIN?

You are likely right that there would be low support for a renumber 
requirement once they exhaust their reserved space.  However, offering 
them a new larger block (with the associated future reserved space) and a 
period of time to move over might still be a good idea since that leaves 
them with just one block of space.

I remember when discussing another proposal that it was revealed that very 
few people have ever came back for another block of IPv6.  Also, ISP's 
could manage a lot of this themselves without the need to request more 
resources by for example only issuing a /64 to each customer by default, 
and only providing a /48 upon request.  Some are only providing a /60 or 
/56 instead of a /48 which drastically reduces use of that block.
