I don't know if it makes sense - technically, obviously there are many ways of providing service, many of which would be more convenient for the customer. On the other hand, commercially BT seem to have done all right with their approach. They've sold plenty so customers must be OK with it. We've had this debate since forever - it was the same with SDH circuits back in the day - you had to accommodate an SDH shelf, PSU and batteries in your rack in Telehouse to get a single E1 from BT whereas other operators would simply run you a coax pair from their suite.
