APNIC has no requirement to return address to IANA. Future actions
directing the IANA specifically related to this issue are non
existent. That means that between the IANA and the NRO, we could end
up with completely unpredictable and undesirable results.

I highly doubt that any address space will ever be returned to the
IANA. Aside from that, the proposal is weak in many areas and is
unlikely to reach consensus in the ARIN region anyhow and IMHO. We
also already have adopted a proposal to address this issue. It's
unfortunate that at least one region opted for politics over
cooperation hence here we are again. What I find most interesting with
this latest proposal is that need seems to be rapidly collapsing as a
concrete basis for continued allocations. YMMV.
