Uhh, I'd say there are a thousand or two such ISPs in the world. That's not insignificant. It isn't useful to be stingy when allocating prefixes to ISPs which _might_ end up needing more than a /32 for their customer /48 assignments.
And if such ISPs decide that rather than going through the process of justifying more space, they end up giving the customers /64's instead.. well, the result might not be pretty.
I think the risk of ISPs handing out /64s is very small. Actually I expect most of the consumer ISPs (and they are the ones with the large number of customers) to hand out /128s. If they started giving networks (and not just single Addresses) to their customers their complete set of "business products" would no longer exist. I doubt the techies are strong enough to fight this through against product management. Nils
