I agree that AoA certainly has potential for GA, but current GA flying techniques (and training & testing) evolved based on other instruments. Individual GA users who have the inclination can certainly acquire and learn to use AoA instrumentation. IMO (and only my opinion) applying it broadly across all GA would require big changes from the ground up, which would be opposed by various interested parties due to cost.

AoA is a getting a more direct answer to the question at hand, but you can still get the answer through other instruments...if I'm flying the proper profile I already know what AoA is going to tell me (except in icing). It would probably be easier for private pilots to scan just an AoA gauge and the runway in the base-to-final turn, but it's probably too politically challenging and costly to mandate AoA. But no reason individuals can't take advantage of it, as long as they commit to learning and using it correctly...otherwise it's just another dust collector, and possibly a distraction.
