I’m not opposed to qualifying some cases where private AS may also work, 
because in those cases, frankly, I think most organizations will either use a 
private AS rather than go to the trouble of applying, or, they may have a good 
reason (future plans, etc.) for wanting to get a public AS and not have to 
re-run all their peering sessions later.
