I have been thinking about how in Medieval times Bakers would often feed their entire community with bread baked in very large ovens made from brick/stone and mortar.
With the Beehive kiln in 1.20 for mass manufactureing of Clay goods it would be pretty neat if we also could build large ovens that can bake much more than 4 breads or a pie at a time.
Moving baked goods in and out with a paddle or large spatua.
It would add a lot to the roleplay to have a village bakery with a large communal Masonry Oven
Edit: this could also give opportunity to add recipies like quiches and pizzas
