Coming from any other modern language has a much harsher friend in default methods in protocol extensions and having code execution once again depend on the reference type in those cases and no protection to tell you that your code is at risk of this occurring (your class method only called if you use the class type to reference the created instance).
The current private is closer to other languages than the previous one we had which now has in fileprivate a better name.
