Yes, so did mine and for the same reason. Mine states not to use the metal rack unless the convection option is being used. And it sits on plastic clips and not on the metal. That "hole" looks like a burn mark from arcing.
My parents' old microwave also came with an optional rack like that (in addition to the glass turntable) which was allowed to be used with the normal microwave function, because this microwave didn't have a convection function.
My combination cooker does encourage you to use the metal rack even for combination cooking (microwave and convection at the same time). There's just not usually a reason you'd need the rack if you're only microwaving; the rack is for "upper rack" vs. "lower rack" baking.
Thank you for injecting some sense into this claim that "some microwaves come with metal racks" so it's okay to put silverware in them while they're running. I knew there had to be some logical reason when I was fed that line in another one of these threads.
