This feels pretty stawman-y to me. They are meant to be highly digestible examples of everything the framework has to offer. They can be read through quite quickly, yet people still fail to and then you have people who don't know what scopes are or reinvent ways to do enums and what-have-you just because they weren't aware this stuff exists already. If you need to drill down into a specific topic, that's what the docs and blog posts are for. Having the level of detail you describe in the guides would only turn-off newcomers even more.
