Generally I think using nested classes for real helper classes that can conceptually only be for use with the parent class is a useful way of avoiding namespace clutter. I'd be careful of building large hierarchies, especially deep ones tho. I feel if your goal is nice decoupling then you want small distinct usable classes/objects. Also I guess if you're more of an agile developer, the hierarchy could discourage/slow down some refactoring. 2 cents A.
