Agreed, but I think there's something to be said for allowing light coupling sometimes. Anathema to "proper" design, but not uncommonly the overall complexity of a proper design makes maintenance harder, not less. I'd rather change a hardcoded SQL query than three layers of abstraction, myself; centralisation beats having to follow a trail of classes, and you always need a good test suite anyway.
