    It’s definitely not required for ovens. You can just open the oven. Source: previous oven (1950s vintage) didn’t have one.

    Pretty useful though, and pretty important on microwaves too since you can’t safely open the [microwave] oven while it’s running.

      How’s it not safe to open the oven while running? Just don’t touch anything without mitts and keep your face back.

      You can open it but you every time you do, you lose heat, which has to be compensated for by the oven. A window makes the process much easier. There wouldn’t really be measurable gains for a dishwasher
