And this is a policy forum, not an engineering one.

BGP proxy aggregation
This discussion from NANOG 11 years ago:
http://www.academ.com/nanog/september1995/proxy.html
leads me to suspect that proxy aggregation is a tried
and tested way of dealing with the future aggregation of
early assignments, as long as ARIN allocates the address
blocks so that they are aggregatable. If ARIN does allocate
these PI blocks from a single identifiable aggregate, then
I suspect that ISPs outside North America will proxy
aggregate these prefixes. Of course, with a little more
effort, ARIN could allow for several regional aggregates 
within North America.

I think you want the IETF mailing list. This is
ARIN's public policy mailing list where engineering
is secondary to policy.
