Having a final class is conceptually different from having a class with only final methods. You can legitimately inherit from a class with no virtual methods and add to its interface and implement other methods using its final ones. The final class concept is extremely useful when you just don't want to be inherited from. For instance, Your class may be closely tied to an implementation and inheriting from it would wreck the implementation.
It looks like a bad usage of inheritance. If you want to use these methods, why not use composition ?
It make no sense to use such an inherited class in a polymorphic context, so why use inheritance at all ?
