A2g was never meant literally. As low as you can go at whatever feet width you use. It's just generally doing the lift in the full range of motion like most every other lift.
And of course like other lifts, sometimes it is smart to train 'parts' of the lifts in order to strengthen the weak points of the full lifts. Like different height boxes for box squats, 2-3-4-etc board presses with bench press, and rack deadlifts.
