Essentially what it says on the tin. Would be nice to add an option, in the same vein as dispensersTillSoil and the vanilla dispenser flint-and-steel mechanics, to let dispensers carve pumpkins with shears. This would allow for fully automated snow golem factories in combination with autoCraftingDropper.

you can just move them away and the villagers will spawn new ones

Yeah and it's not like there is already an in-game mechanic that can produce infinite iron golems.

Couldn't you use an iron farm, and just don't kill the spawned golems?
Or would their continued existence prevent further ones from spawning?
