Don't know all, but have you see the arp tables on a PE router? Have you 
seen some of the crazy things devices other than routers can do on 
ethernet? There are many advantages to CE routers. SP controlled CEs 
take it even further in managing demarcation, other services, and 
offloading of any service level restrictions to the CE.

Also, I believe on ethernet, some SPs do layer 2 level security and 
filtering which is made easier when only 1 MAC per CE.
