I am very picky about maintenance, service, and safety of my cars.... Well, I haven't put brake pads on "thousands of times" in 40+ years, but many times without turning the rotors. I agree, I don't have the rotors turned unless there is a real problem with the surface. I have found that if the rotors are warped, turning them only fixes the warping problem for about 50 miles. That's just my worthless opinion. :D
