Then a third? The fact whether there is a use case or not, or whether I have one or not should be irrelevant. The issue should stand on it's own. Having some easily way to use multiple variadic parameters is either useful or not.
There are a mind-boggling large number of things that are useful, but that's not the criteria for adding something to a programming language.
A new feature has to be *sufficiently* useful to justify the increased complexity of the language and it's implementations (plus not clashing badly with other features). Example use cases are a useful way of demonstrating just how useful a feature can be.
