Die by degrees
So no hatin' here, the aircraft flare/dimples were established waaaaay back as MS (Military Specifications) once the CAA (now known as the FAA) came into being the angles, fasteners, alloys ect were pretty much set. SAE developed the new angles in an attemped to prevent cross pollenization as they say.
As explained to me by a Airframe and Powerplant instructor. Might not make much of a difference to a car guy till they look out over a wing at 30,000 ft.
