Ah, but it's not structurally integral, it's stylistic and should ideally be kept separate from the structural code. It's good practice and it makes it easier to find where the file's being included.

Plus, people may have their own versions. I do, I have a couple of typography sheets and quite rarely use ones included in a framework.
