(f) regarding "aerodynamic breaking" (and the typo was intentional) I would invite anyone to present verifiable test data which even suggests that that sort of technique is better than a good bootful of braking ... (looking at the serious short strip requirement)
The idea is to use both. Obviously if you're too fast and try to hold off in the flare in ground effect, you will chew up valuable strip. In a lighty it's pretty easy to fly the last 50' or so just above the stall (taking into account wind conditions) so that you are able to touch down right where you want to, at very close to CL max, and therefore min speed, and high Induced Drag. Then you can stand on the brakes (after the nose touches down) which will be much more effective at this lower speed (with full flap, an extra 5-10 knots at touchdown gives a significant reduction in braking traction).
In general I think the retraction of flap before the aircraft has slowed to taxi speed is poor practice, particularly in a retractable aircraft. But there are situations and aircraft types that may warrant it.
