I guess the real question in my mind is whether there is any true gain in symmetry or readability by doing it this way.
I think there's a small gain: everything else being equal, an API with fewer functions is easier to use and easier to understand. If we can provide a single function that takes the place of three functions without losing anything, we ought to do so.
