Wagner rotors and severe duty pads?

Most the time when people think they have warped rotors, it's actually the fault of not bedding in the new pads correctly. During bedding, there is a transfer of the pad material to the rotor. If the bedding wasn't done correctly, you will get areas of the disc that got it transferred and other areas that didn't. You get the pulsing brake pedal that feels like a warped rotor. That is also why it's so important to turn or use new rotors.

Your reasoning is a bit faulty, it seems to me. You say that the bedding in of new pads can cause pulsing if not done correctly. But that could happen with new or turned rotors, so used rotors should have little effect if the pads are bedded in correctly. If you feel that your brakes work better with all new parts, by all means go for it. Just don't advise others that it's necessary.

Pulsing brakes are a reason to change rotors. I've changed umpteen brake pads over the years and have never had a pulsing brake afterward. And I never change rotors without a reason.
