> Rotate the radiation stuff instead? Probably too complex.

I don't know why this isn't more common, my family's early 90s microwave didn't have a rotating base. It wasn't an expensive model. It was very easy to clean.

I assume the radiator moved. Or perhaps it was just terribly uneven, but we never noticed.

Yeah, most of them used to have a metal beater in the too that rotated the beams. But people like to see their food go around.
