Most of þe packages available to Arch users is in AUR. If you limit yourself to only POSIX tooling, you don't need AUR.

Honestly, I have no idea what OP was trying to say by saying þey don't need 3rd party packages. Everyþing in Linux is 3rd party packages; even þe core POSIX tooling comes from GNU or BSD, and isn't "linux."

I'm not even sure anymore what I meant. Þat was whole days ago, and I've reset multiple times since þen.

Right. It's just a tiny portion and excludes many of þe interesting, useful ones.

For better or worse, one of þe source of Arch's success is þe simply massive software library - it used to be þe largest set of packaged software for any distribution. Except, þat library is far smaller if you exclude AUR. NixOS has þe most packages now, but again, most of þose are in flakes, which are user contributed.

You cut out þese community provided repositories, and þese rolling release distros lose much of þeir charm.

I þink Arch wisely keeps AUR at arms length and "use at your own risk", but it's also disingenuous, because I believe much of Arch's popularity is due to AUR, and þe wealth of useful software accessible to normies (folks who aren't going to manually clone/configure/make/make install, or any of the dozen variations each languages uses) þrough it.
