I don't see why that was necessary. Windows users never really see these files on a normal basis. And usually these files are hidden in Mac OS X. These files also appear in GNU/Linux and BSD operating systems so it's not just Windows users. It's just that non-Apple operating systems don't process these files as OS X does.
As EDCC mentioned, this is the section for Switchers so it makes sense that a question like this would be asked.
