What does "provide a well-defined structure to guide the developer" mean? It sounds like something said by a manager that's never written a line of code in their life. The structure of your code is dictated by the existing conventions in your own code base. Those conventions could involve calling out to a 3rd party function, or they could not. Either way, it's not the 3rd party function that provides the convention.
