Yup. Actually though about that possibility while writing this. Quite like I would not use a function argument if I don't need it. So I would avoid putting these parameters in the function signature in the first place. It just leads to confusion at best, and there's a good reason why many compilers emit warnings for this. I believe a function should only take the minimum it needs, and I believe APIs should not be different in this matter. Redundancy is good when you actually need it, and not quite when you don't.
