Well, actually for an ISP it does. An ISP wants to be able to do queueing 
bidirectionally on the customer facing interface in the case where no 
dedicated CPE is available, ie when you do L2 aggregation directly into an 
PE router.

I know hw manufacturers doesn't see it this way, which is sad. Having to 
purchase an expensive L3 CPE just to be able to do bidirectional shaping 
might sound good if you're an equipment manufacturer, but as an ISP I 
would rather not have a device that does a lot of critical things for my 
business, placed at the customer prem. The customer has no interest in my 
shaping them, but I do. They have an interest in their connection working 
what so ever, so having something managable at their prem so I can monitor 
my connection to them makes perfect sense though.
