Wow! My take on seat tilt? The right tilt is based on my seat, my butt and my riding position. Your thoughts about it never enter into the picture. The idea of changing my seat tilt from the most comfortable to please you or other riders never crosses my mind. All my bikes have nose down seats to varying degrees. Yes, I ride with weight on my hands (except when I am riding hard). It requires a little strength and a little conditioning. Is that bad? Since no work is done, energy is not burned by the weight on my hands and since I can ride a more aero position, less energy is burned by my legs. That sounds and feels like a net gain. (When I hear that weight on the hands is bad and tiring, I think "Man up! Grow some muscle!")
