Yes, this is why I emphasized the "install and go" aspect of Manjaro. It requires a certain amount of "opinionatedness" by the maintainers, which of course isn't a priority for Arch, which is also fine.
I saw and understood the reasons for scrapping the beginner's guide. I still disagreed with it. All I saw was that the Arch community was unwilling to provide for beginners. Yes, it's a lot of effort and it is to a degree duplication, but it's duplication in the same way that Simple Wikipedia is a duplication of Wikipedia. It sort of is, but it sort of isn't.
It's duplicated effort, definitely, and if you don't prioritize onboarding beginners, then it's also wasted effort. But as somebody who personally used the guide a lot, as somebody who takes no pleasure in scouring through 5 different 30 page long wiki pages to find an answer to something trivial, the documentation as is simply isn't an adequate replacement for the beginner's guide. I've accepted that the Arch community has decided that it's the best solution, but I won't stop criticizing them in discussions like this for sacrificing such a great resource just because we happen to have different priorities.
Ubuntu gave me simple install. Once I've started tinkering it become broken. Following Installation guide and Beginners guide I got stable system with internet connection without Gnome toolbar widget. I could build on top of it.
These days I stick with Arch because of fresh packages, rolling release, makepkg and AUR. Just looking at https://wiki.archlinux.org/index.php/Network_interface is enough to stick with wifi-menu / wpa_supplicant.
I gather that you simply want something more opinionated than Arch, and that is OK, even the BSDs have a more opinionated install procedure than Arch.
But FTR scrapping the "Beginner's guide" was done for really good reasons: it duplicated the content of other Wiki articles, which is a maintainability nightmare, and was too opinionated for Arch. All the content should still be accessible by wiki links to other Arch wiki articles.
