I'm not 100% sold on the decision yet but since I've switched to Arch Linux, I'm not sure if it's worth maintaining Debian / Ubuntu support as well as other distros if you bring your own packages. macOS support will continue because I use it on a work laptop.
Non-Arch support doesn't add a ton of complexity to the project but it adds a bit here and there and also requires extra testing.
I'm kind of curious how people are using these dotfiles and for which Linux distros.
