Didn't read every post in detail. I just skimmed. My response to anyone who claims there's a big pull deficit in S&S may not be one-arm swinging a big enough bell with good mechanical form. Done properly (engaging lats, packing shoulders, keeping both shoulders square), they will work your lats.
As far as bicep envy, take the overlooked, goblet squat. If done slow, with a big bell, they will probably work your upper body more than the lower. The isometric hold (on the horns) of a big bell will work your biceps. If you're stuck with a smaller bell, then do the curls at the bottom.
S&S is GPP, and it's a great program to build a base of strength. Sure, there are better programs/exercised to hit the upper body pull, but to say S&S doesn't cover it is false.
