I see a few up-sides.

You get clean /56 handoff to customer, and you don't need to have any of 
the customer GUA addresses on the ISP router, meaning control plane 
protection is easier. You also lessen amount of table entries you need for 
uRPF.

Downside:

People actually need CPE, they can't connect a computer directly (at least 
not without turning on Internet Connection Sharing or alike).
