Yep, +1 for this approach. I would intuitively expect that, if I omit variadic argument(s) when calling a function, that the function ends up getting an empty array of the appropriate type. And when writing a variadic function, I wouldn't find it all surprising or annoying if I was not allowed to override this default. In the unlikely case I want my function to do something special when it gets an empty array, I can write that behaviour into the function body.
