The problem is this can get pervaded quickly.

In most extreme cases, the 'example' is literally only useful for hello-world style things, and anything more complex requires digging deep into docs to understand (I can think of at least one .NET library where this 'blogger-friendly' API structure exists...) And then as alluded to, every example shows this simple case that doesn't help anyone know how to configure things in ways that are testable/etc.
