Hey Now it is a time for CI Team to prepare and write a CI 4+ Tutorial Book

That's very similar to a personal project I had started in the past. No official forums, all of the organization happened via tags.That does require other things to make it usable though, like Rooms if you want to be able to make a "forum" restricted (like for admin discussion, etc), and a very good search engine. The challenge becomes finding stuff within the thousands of posts, so you still need to be able to browse the content in some form of organized fashion, but handling it like Flarum does where you can see a hierarchal list of tags and filter by the tags handles that pretty well.

If this is something we're seriously interested in doing, we should take the discussion off of this thread at the least. Maybe plan it over at the repo's discussions?

That's fine by me.
