There has to be a hole for radiation from the magnetron. The perforated holes on the front glass are much smaller than a wavelength, and that wall looks essentially solid. That would be true for other holes (although the seams along the door, being long in one dimension, can leak radiation). I had a colleague at MIT that made lots of money selling “radiation detectors” for microwaves to gullible people who thought that this radiation might hurt them.

OK, just one question: Does the basic design of a microwave oven require that the interior have holes in it? Those holes make it inevitable that as time marches on the oven starts to stink.

No excuses for the user interfaces. For the inner surfaces, however, I’m pretty sure they are intended to randomize the distribution of reflected internal radiation, which would, with smooth surfaces, likely bounce in very predictable ways, leading to local hot spots and cold spots.
