I think such a policy would be a bad idea. The fundamental problem I have with this text, is that it assumes all downstream customers are equally valuable to the ISP. For instance, an ISP might wish to reserve IP addresses for a high-margin aspect of their business - perhaps even at the cost of losing other customers. This policy might result in artificial incentives that ultimately harm the ISP business, reduce competition in the ISP market, etc.
