So Provider A announces his ten /15 CIDR blocks to Provider B, aggregating
huge numbers of IPs into those ten announcements.  He then wishes to
announce 20 "bad" prefixes from customers of /21 or longer.  Under your
plan, that doesn't fly.  Why is it that we assume that a "large" provider
has to be announcing many routes?
