I thought that also, but just becuse you can "alreayd do it" doens't mean there isn't a better way or shouldn't be a better way. For exaple, C++ (for the most part) is C with a lot of shortcuts, and cut corners. Such as why did C++ feel the need to add cout, when printf already existed? You can print everything you want with printf, So why add cout?
It's little things that are nice in the longrun that make thigns enjoyable. Even if it can be done otherwise, the shortcuts are nice >:D
