The challenge is that there's an indeterminable point at which the "cheese" stops being an integral part of the burger. For a "cheeseburger" cheese is obviously integral. For a Big Mac, it's less clear but a "plain" Big Mac usually includes cheese. For a fancy place's "deluxe Wagyu beef burger" that has cheese/truffles/a bunch of other stuff, a "plain" version will likely not have cheese.
