I will add to that point that the Nice classification system is a little bit odd by today's standards. For example, metal garbage cans and plastic garbage cans fall into two different classes. In a system that moves toward a per-class fee, you would end up paying a lot more to cover garbage cans of all types than to cover one or the other. There's not necessarily a sensibility there.
