I acknowledge that there are practical limits to my theory, such as running an engine outside of the efficient range, and wind resistance. However, I don't see any evidence to support the theory that going as slow as possible up a hill is best.
No not arguing just that from experience if you drive a car up a long mountain pass at maximum engine output it will take much more fuel than if you take your time. Even with the time difference the overall fuel consumption will be higher at full burn.

I once owned an 85 Jetta diesel that would pull the local mountain pass all out (in high gear) at 65+ MPH. Slowing down to 50 and dropping a gear resulted in about two thirds throttle and much better efficiency. Driving an underpowered car like the Jetta (52 HP) teaches you a lot about shift points, energy conservation etc.
