I'm surprised so many people who want to use Arch aren't in it for the fiddling.
I've had publicly installable dotfiles with a "1 command and ~5 minutes later" you have your development environment set up for a few years now. It is command line focused since my main box is running WSL 2 with Arch Linux. The script works for Debian, Ubuntu, Arch and macOS since I use a work laptop that's running a MBP.
It was a lot of fun building things up and learning about the process as I went.
When I got a laptop to install native Linux a little while back, Omarchy was just coming out and I figured ok since I will want a solution to trick out a window manager / DE I'll want more than command line tools so I took a look.
I ended up avoiding it for a few reasons but the main one was I don't want to ask for permission or maintain a fork to deviate from the Omarchy defaults that cannot be customized without a fork.
I love Rails and the philosophy behind it but I don't think the same model applies to something as intimate and personal as your OS. Your OS is more like a custom application made for you, especially if you're going down the Arch (or Linux in general) route.
