Does Arch have an official package manager yet? Was extremely weird to try it out last year and want to install some AUR packages, and every package getting tool seemed to describe itself as deprecated or unsupported.
Interesting, having used Arch for several years now after previously having used Ubuntu and Fedora, this isn't my impression at all. In particular, there are a lot of nonfree things that are in the core Arch repos that Ubuntu and Fedora don't tend to include. I tended to need things that weren't in the repos at least as often on Ubuntu as I do on Arch, but had to use either third-party PPAs or compile from source to get them.
Objectively speaking, Arch has ~60K official packages, which is more than Debian and Ubuntu at ~50K each. I don't think many distros even have more packages than Arch. The official repos aren't tiny at all.
Automating AUR updates is asking for trouble anyway.
