You are entitled to your opinion and maybe I am wrong but I don't believe the rotor hat is going to expand appreciably when sandwiched between the hub surface and the wheel. Which are also going to expand. And even if it did, the difference in the expansion between being sandwiched with the correct 96ftlbs of torque vs say a mis-torqued wheel at where some lugs are at 120ftlbs of torque is not going to lead to appreciable distortion of the rotor hat.

Secondly on a street car you are never going to experience the types of temperatures you refer to in race cars. I would be pretty concerned if I saw someones rotors glowing red hot at night on the exit ramp as you see at night during Le Mans. The most common way people warp rotors on the street is when they run them too thin or they do some heavy braking and while the rotor is hot they still have their foot on the brake, thus the pads make contact with the rotor both melting some pad material to the disc and/or resulting in differential cooling of the disc leading to warping.
