For example, they even put a green ground screw on switches

You are only properly grounded in a metal box if the device is listed
as self grounding (a spring or brass clip on the yoke)
In a plastic box, there is no guarantee the plate will be plastic and
you still have metal screws. Before the grounded switches, *they only
allowed plastic screws on switch plates but that rule was not followed
much either

.In almost 60 years I've NEVER seen a plastic plate screw.

Yes, I've seen and used plastic plate screws too.
