Only 1 question: What about the companies that have a /24 out of the /20 0r /21 that are = multi-homed? If the route rules are not carefully prepared the multi-homed customer = then might be single-homed and tied to the upstream they got the IP's = from.
Thoughts?

I'm not seeing any scenarios which would differ from the existing practice of filtering out said /24 entirely. Depending on how a particular entity heard the /24, they may even continue to accept it as such without aggregation. For example, if the company was announcing the /24 to a peer of a network using this type of aggregation, the peer would still see the route as a /24. Otherwise, they lose nothing by aggregating to the /20 or /21 along their transit path.
