The original design of the filter base class required several specialized base classes to control what information was pulled from the input `DataSet` and provided to the derived class. Since the filter base class was redesigned, the derived classes all get a `DataSet` and pull their own information from it. Thus, most specialized filter base classes became unnecessary and removed. The one substantial exception was the `FilterField`. This filter base class managed input and output arrays. This was kept separate from the base `Filter` because not all filters need the ability to select this information. That said, this separation has not been particularly helpful. There are several other features of `Filter` that does not apply to all subclasses. Furthermore, there are several derived filters that are using `FilterField` merely to pick a single part, like selecting a coordinate system, and ignoring the rest of the abilities. Thus, it makes more sense to deprecate `FilterField` and have these classes inherit directly from `Filter`.
