The nose gear "ended up" short to facilitate shorter takeoff runs,
actually. By reducing aircraft incidence, the wing operates at a lower
lift coefficient during roll and thus incurs less induced drag. Less
drag implies better acceleration, except the thrust line gets inclined
downwards or the intake performance is impaired by this measure.
