Downstream shaping is totally about cost control, it was there to reduce the investment required in peering and transit capacity to support uplifted services and reduce stress on the existing occasionally overloaded capacity and has failed quite abysmally to do so as far as I'm aware.

The shaping in either direction isn't focussed or dynamic, it's even worse on upstream. To focus it properly would require the shaping hardware to be aware of each and every interface on the network which they most certainly are not.

The question of good service is a non-issue, if shaping is required for service quality to be maintained off-peak there are other issues and shaping shouldn't be used to try and cover them up.
