It is closer, but it's not a goal for Swift to always follow conventions of other languages. It's useful sometimes. But in this case it goes directly against the philosophy of Swift's extension feature. Swift should be allowed to go against the norm when it serves the languages. And in this case, if only one private should exist, it's the file-s open one.
