I don’t tend to think so, as a general rule. Interfaces matter so components can cooperate but the internals can, and generally should be, treated as a black box. It’s like connecting chips on a board. The actual code is more like painting a landscape. There are techniques for representing some idea and many can be chosen. It’s up to the artist to choose the one they think works the best. So long as the interface to the world outside is solid, it usually doesn’t matter what happens inside. For instance, if I had an interface to write data to a file it may have time constraints. So long as they’re met, all is good.
