I think some of us airline guys are merely trying to say that large rudder inputs, other than for assymetric yaw conditions, are pretty much unheard of. Possibly in an "upset" condition if it helps to pick up a wing and/or prevent further yaw. I'm not an expert but I've never heard it suggested as an appropriate response. In a vortex encounter I'd expect to use aileron primarily.
Light aircraft may need an appropriate rudder input and I've spent a fair amount of time teaching "co-ordinated" controls. If you're teaching in an aircraft with barn door ailerons that are prone to aileron drag then it's essential. Perhaps that is where your confusion is arising?

I suspect all the Boeing FCOMs were amended after the AA crash.
