There are many other array functions that work with keys using this naming pattern. This would make it clearer in the code what is being filtered, and no need for the additional parameter. In this case I think I would still prefer it if the callback took a single parameter. Values can still be easily looked up with $array[$key] in user defined callbacks, but all of the built-in functions that take a single parameter are still available to use.
