This mod disables some common automated farms, specifically:
Villager powered crop farms: it makes it so that farmer villagers don't spawn drops when they harvest crop. Instead, the items are instantly transferred into their inventory. Can be disabled from the config.
Sugar cane/bamboo/cactus farms: the config allows you to choose a list of blocks that only drop items if they're broken by a player.
Pumpkin/melon farms: the config has a list of blocks whose piston moving behavior must be changed. The blocks in the list are moved by pistons instead of being destroyed.
It's meant to be used in modpacks in which those farms are bad for the balance of the game.
