The beauty of having an option is that people can choose not to utilize it. You are certainly free to dither every frame if you think that is best. However, I thought I made a compelling argument, including mathematical examples, that skipping dithering can improve image quality if done properly. Unless you have some sound mathematical argument to the contrary, of have found a flaw in my reasoning, I stand by my assertion. I find the argument that you've been "doing it that way for 20 years, therefore it is right" to be lacking.
