Granted, some use "f8", "f11", and "f16", but in a mathematical sense they aren't the correct expressions for the diameter of the aperture.

While you may be technically correct, you are arguing semantics now. "16" is not a smaller number than "11" even if the mathematic area it represents, is. The numbers are what are printed on the lens, so by convention that is what is commonly used. Anything else is just more confusing. Practicality must serve some purpose.
I liken it to most people don't have to know what goes on in a high combustion engine to be able to stick a key in a hole and make their car go. Let's use the KISS principle.
