It was common practice to fly the L2 in 3 axis as the IAS hold was quite poor. To fly 4 axis, you had to be very gentle with any speed changes or the aircraft would exchange altitude for speed. During a 200’ ARA this could be quite exciting. There’s no issue flying 3 axis as long as you monitor and apply power as the aircraft levels. Have I ever had to remind the PF to raise the lever in 3 axis...yes.
