There's an important distinction subtly hidden here. Carrying & advertizing
a shorter prefix most likely provides reachability for more end-point
destinations, which in turn results in more traffic transiting the
advertisement path towards the destination.

As Alan suggested, this is a key argument for PIARA proponents, in that
advertizing a shorter prefix = advertizing more end-stations = more traffic.
