This responds to some feedback on the forums. Most importantly this allows for us to use variadic generics in the the type system to document whether we allow for "appending" behavior or not. Previously, for some options we would take the last behavior (and theoretically) for others would have silently had appending behavior. This just makes the behavior simple and more explicit.
