6 days ago I probably should've provided more info on the issue.
Saturation formula in minecraft is: nutrition saturationModifier 2
Neoforge's .saturation() already provides value by that formula (so 1.21 changes were not needed), but in 1.20 saturation is still not what it should be. I made a pull request to illustrate, if that helps? #1506
It calculates mana like this: mana += 30 * food.getSaturationModifier();
instead of plugging in the saturation formula, making gains from saturation miniscule, since modifier is 0.6 for most items.
