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.
