Xcode new generates an empty category. Why?
===

I noticed this while using iOS6 beta 3

When I create a new subclass of a UIViewContoller (no other parent classes generate this behavior that I've noticed), the .m file now has an empty category at the top of the file. In the past when learning about categories I noticed that some people would use this same technique to indicate private methods (although not truly private). 

Is that what the intent is here? Has there been any change to making things actually private now? I notice the @private directive out there too. 

What is YOUR PERSONAL coding style regarding private vars and methods?
