I enjoy Cargo and DPL, they're powerful and great tools for automatically aggregating and filtering content, and I used both of them a lot at a MW that I was an admin on for several years. But it still isn't easy to build an ordered, hierarchical, book-like structure with book-like output, which was a constant request. It wasn't just technically complex (no users wanted to learn how to do it, they wanted one person to do it for them), it also didn't do the one thing most people wanted it to do. The Collection extension did that, though, but Wikimedia's weird behavior around it and their multiple failed attempts at choosing a tech stack for output — OCG/ZIM, PoD/PediaPress, Electron (not that one)/Proton — much less the next step of building that functionality into a usable feature in MW, turned me off from trying. I need to dig into BookStack (I imagine like most wiki flavors, it'll lack the templating features in MW that I rely on), but the fact that it's built on the book/chapter paradigm from the ground up instantly catches my eye.
