That's simply not true. Many ISPs will advertise another's netblocks for a
mutual downstream. The client doesn't have enough IP space to qualify for
PI space in any case unless they utilize a /21 to 80% while being
multihomed.
I don't see the logic behind refusing the customer a request of this sort.
