Do you have pretty near-term plans to introduce DXContainer-specific options? If not, perhaps it's worth adding a comment to clarify why this is here. The only reason I can think of is to give something for `getDXContainerConfig` to return (and we still want that function, because it's the place to put the "not supported" errors.
