Always point for server? Hardly. Most of the lets I see are of the kind where the ball trajectory remains relatively unchanged. The amount of points where the serve would turn into a perfect drop shot is low indeed. With a high bounce on the net it might even set up the returner for a winner, provided he's quick on his feet.
