I think a global policy has too much overhead and it doesn't actually
work for this purpose anyway.

I will guarantee you that the other RIRs will be informed of the state
of this policy in the ARIN region if it passes. I will also guarantee you
that if this space is publicized as being available for shared usage
by ARIN, the other RIRs will encourage their registrants to make
use of it where applicable.

Every RIRs policy development process includes an analysis of
each proposal that includes the state of similar policies in the
other regions. If this were proposed somewhere else after it has
passed in the ARIN region, that analysis would show that the
ARIN space has already been reserved and made available
for that purpose.

Can you provide a reference to this? I know about it being shot down
in IETF, but, somehow I missed it if it was on any of the other RIR policy
mailing lists.

I can assure you that the other RIRs will be made aware of it if this
policy passes in the ARIN region.
