Since the game can be played in peaceful, I would suggest adding the mod HungerInPeace, so the player still has normal hunger and fall damage mechanics while not being bothered by mobs

As noted this doesn't really fit with the peaceful mode goal of "just let me build a factory in peace." You're free to add it to your own instance as it shouldn't break anything I can think of, alternately you could play on non-peaceful and change the vanilla game rules via commands to disable mob spawning.

That is completely unneed in this pack, this is a Tech automation pack you shouldn't even been bothered by having to get food if you play in peaceful, at least imo
