What I have seen time and again in modeling is that you start out thinking you can use a simple literal value, but later you find it needs to become a composite. Say you are modeling a project. It has a budget, and that's just a number, a literal value. But soon you need it to have a capital improvement component and a maintenance component, and you find you also need it split out into quarterly segments. Your nice simple literal has become a complicated construction. So you might as well plan on that happening, to make it easy when it does.
