You would do well to use a more measured tone in your posting because this is an interesting question. Alas, I suspect you are not interested in discussion so much as a shouting match. However, I will refrain from such contrivances and attempt to answer your question. Please do the same, should you choose to respond.
The use of sumo deadlifts in the book is reserved for those whose shoulders are below their hips in the conventional setup. This is a very rare anthropometry, however. I have seen it no more than about four or five times that I can remember in the last several years. There may be others for whom sumo pulls, or other deadlift variants, are appropriate, but that is beyond the scope of this discussion. However, to clarify the example in your post above, there is a very specific case Rip talks about with respect to sumo vs. conventional and that case is rare, indeed.
To address the squat, you assume that there is a "superior body position" that we could instantly recognize in the squat. I am not sure what this would be. I have never seen someone get their shoulders below their hips in the normal course of squatting, even those with anthropometries that would preclude conventional deadlifts. Some people lean over more in the squat than others. This is not inherently evil. You mention Layne Norton, who squatted 303 kg in the 93 kg class at IPF Worlds in 2015, which happened to be a world record. Layne leans over a lot, but, once again, I don't know that is bad in and of itself. While looking at the best in the world and trying to emulate them is not necessarily a productive exercise, would you advance an argument that Layne would squat more weight if he emulated Carl Yngvar Christensen, who also squatted a world record (albeit in a single ply suit and wraps) using a more upright high bar technique? I would not. All we can say is that strong people are strong and that there is a fair amount of variation in the techniques they use to squat in competition. I don't think there is an ideal body position in the squat that is universal among lifters with varying limb lengths. For each lifter, there is probably an ideal torso position on each squat variant that will change based on bar position. Lifter A's torso angle will not translate to Lifter B, unfortunately, unless they are clones.
I can assure that my mind is not blown when you mention that long legged people lean over more when they squat, or that their high bar squats have similar torso angles to the low bar squats of others with shorter legs (assuming similar torso lengths). Since they are already leaned over, why not put the bar lower on the back with the additional support of the tightened upper back musculature that low bar provides? Why not use hip drive since they are in good position to do so and would likely be doing the same with a high bar squat? Putting the bar below the contracted posterior deltoid is generally not possible for most people. I don't believe Layne Norton does this, either. The bar would want to roll down the back.
Lastly, be nice. I have followed my own advice here, despite your tone, and ask that if you want to discuss these topics dial things back and perhaps this thread will go somewhere useful. If not, I reserve the right to delete postings or lock the thread.
