Why did we do this? Without this policy, any space returned to the
IANA would be stranded, because we have triggered the allocation of
the last /8s from IANA, it's questionable as to what would happen to
returned space, because there's no current mechanism for IANA to
distribute space to the RIRs, especially space that's smaller than a

Is this factual, or does APNIC have a policy requiring the return of
unused space to IANA? Would IANA even accept returns at this point?

As evidence to that, Interop returned almost a full /8 and their press
release is quite clear, I'll read it from it here: "After the hold
period, ARIN will follow global policy at that time and return it to
the global free pool or distribute the space to those organizations in
the ARIN region with documented need." So, I think it's very clear
that if there is a global policy in place that allows ARIN to return
this space to IANA, they will do that, if they think that's the right
thing to do.

I for one, do not.

Basically, it's been adopted in the ARIN region and is under
discussion here and in the others three regions.

It has?
