Crafting Golem, a way to automate crafting

The crafting golem would be made by placing a pumpkin on a crafting table, or similar to however the tuff/copper golems were going to be made. Once made it starts wandering around, however when you right-click it, it will open a menu. The menu will look similar to a crafting table with the addition of a checkmark button. The player can put items in the grid, in the shape of whatever recipe the player chooses, the item will appear in the slot to the right to show what the recipe will make. When the player clicks the check button, the menu closes, they get their items back, and the golem will get to work. When it has a crafting recipe, the golem will wander around looking for the required ingredients. When the golem gets enough ingredients to craft the item, it crafts the item and drops it on the ground. I think this would be a good mob for minecraft because it would allow crafting to become automated, which would be revolutionary for many parts of the game. I also think the crafting golem would be able to work with the allay quite well, with allays delivering ingredients to the golem and taking the finish products to a chest. Also it may appease that one person who keeps putting small, villager-like golems into the mob votes...
