So as APNIC policy currently stands, any additional space from IANA
under this policy would be subject to the last /8 policy and APNIC would
be unable to issue it except to new entrants that hand't already received
a /22 from the final /8?

My bet is that would change, likely without changes to the transfer

Understood... This stage is not the issue...

Would this apply to space that came from IANA after the final /8 under
the proposed global policy we are discussing, or, would it only apply
to the final /8?

I've read both and there is definite ambiguity as to how space received
by APNIC under this policy would be treated (whether or not it would
be subject to the last /8 policy). If it is not, then, the juxtaposition of the
two policies (which were clearly written with the assumption that there
would be no more space coming from IANA after the exhaustion of
the IANA free pool) could create the result I described.

In any case, while the ambiguity of existing APNIC policy in light of
this proposal is of concern, Chris is right that any RIR could pass
a policy with such a damaging result (intentionally or through such
accidental ambiguity as appears to be the case with APNIC). As
such, I would not support the global policy without this protection.
