Would you say rudder only once the stall has been recovered? I.e. nose forward, power on, roll wings level and neutralise yaw once recovered and climb established?
If you think about it as soon as you apply a power change or a pitch change that effects airspeed you will need a rudder input. Personally I don't have a problem with using rudder to arrest a wing drop, but there is a fine line between that and picking a wing up, which you will see on Genghis' things you can do wrong list.
The idea of forward stick/ yoke and then rolling level is that you can't stall at 0g, and you can't bust your rolling g limit, but you can use full aileron to roll level as quickly as you can.
It's fine to say you won't use rudder when you are stalled, but for the sake of a PPL skills test, I don't think an examiner would want to see you delay adding full power, because that is part of the "standard" stall recovery. As soon as you add power you will need a rudder input.
