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.
