Sure--if the sizer actually matched the dimensions of the bin, I think you'd see a lot less pushback. The problem is the current policy is arbitrary and unnecessary, and people don't like policies that are arbitrary and unnecessary so they try to "cheat" instead.
brp's approach to a new sizer, for example, would let through the "slightly larger than the current sizer" bags while not allowing anything that wouldn't go wheels-first into the bin.
