That's very true, but, postponing runout in other regions while leaving
APNIC to suffer under this global shortage will not help the situation and
it is not good stewardship.

Route filtering options are going to be impacted just as adversely by
in-region transfers, so I don't see inter-regional transfers making any
difference here. This is a red herring.

Since geography != topology, I'm having tremendous difficulty seeing
how that would actually be useful even in today's world. Further, there
are already lots of ARIN (and other RIR) recipients using addresses
in other geographies (which is perfectly legitimate use under certain
circumstances such as a US company that runs a global network and
uses ARIN addresses for all or most of their network).

So the above paragraph is also a red herring relying on assumptions
not borne out by reality.
