Even A320 FCTM advises against aerodynamic braking as it is inefficient and in all airplanes increases tail strike possibility. Aerodynamic braking comes in the picture if normal braking has a problem like hydroplaning. That too to get some deceleration till wheel brakes get a grip. A point to consider is the purpose of spoilers on touchdown which is to kill the lift so weight of aircraft is on wheels which increases the braking. But if we increase the AoA on wings it will negate the effect of spoilers. So it not recommended in normal circumstances.
It is not recommended to keep the nose high in order to increase aircraft drag during the initial part of the roll-out, as this technique is inefficient and increases the risk of tail strike. Furthermore, if auto brake MED is used, it may lead to a hard nose gear touch down.
