As someone who will be working in the film industry in a few years, I appreciate what you're trying to do here and agree with you. However, not supporting preservations etc. simply because they use noise reduction is a bit arbitrary - for example, the X0 project is using noise reduction to get rid of video noise added in the telecine and post-telecine processing, while trying to undo the DVNR done to the film in the first place. "Noise reduction" in general doesn't automatically mean removal of film grain, so don't judge until you see the final product.
