100% fine with it.
I generally try to avoid doing it -too- much because I don't wanna spend all the time I'm working on the setting going back to retooling classes, 'cause I have a tendency to iterate my settings repeatedly, and changing the class in iteration 3 means changing it again in 4, 5, 6, and 8.
I generally just get the setting together and do setting-specific subclasses and the like.
