As I understand it ARIN does not like to reclaim space forcibly for this
very reason.  It's costly and they'd much rather resolve matters
amicably and allow people to keep their resources.

It's true that anyone that does accept terms to their IP allocations
opens the possibility up, but recall that ARIN has a open and public
policy making process.  If they are going to change something and begin
demanding IPs back from certain holders, if you are attentive to the
process you should have plenty of opportunity to a) find out, and b)
make your displeasure very clear.  If you are a member, paying your
dues, you also have the right to vote for those people who make the
final decisions.

But more to the point, how often do you hear that ARIN has decided to
come to any IPv4 holder and just take back their allocation without cause?

This is the current policy, even with respect to IPv4 to a large degree,
at least for ARIN.  As long as you can establish a fairly evident need
for portable address space and can give them a vague plan for allocating
it over time, they'll give you want you want, as long as you can pay the
appropriate (and I feel quite reasonable) annual fees.
