On the 737 we have pitch limit 'eyebrows' on the EADI when the flaps are down. This indicates the pitch angle corresponding to pre-stall buffet. As you pull g, the eyebrows move down (obviously) - it is very clever. The main use of these is during evasive manoeuvres when ground contact is imminent - Windshear / GPWS. The SOP is pitch to the PLI's (pitch limit indicators) and apply full thrust.
Very interesting point - the Navy use a 'dohnut' I believe which corresponds to 1.3Vs (or 0.6 of alpha max) for approach.
AoA has nothing to do with V1 as you are still on the ground at decision speed.
