Looks to me like this is getting a reasonable hearing.   I don't mean
to suggest that there's consensus, but your argument that "Nobody
listened when I suggested this a long time ago in a galaxy far, far
away," does not indicate that it's not worth hearing now.

PPML is an excellent place to develop a policy proposal.

If one could demonstrate a high probability of aggregation, that
would help.

There's a window between getting an ISP assignment and an ARIN 
assignment (/29 to /21).  Within that window, I-as-network-admin
would rather have geo<foo>ical provider-independent space than
provider-aggregatable space.  Well, not me personally, since my
network is NATed behind a /28, but I could imagine people thinking
that if they have to renumber at /21 anyway, at least regional PI
addresses would keep them from having to renumber in the meantime.
