Why does it need to be maintained? It's just an install script to install common apps on Arch and to install and configure Hyprland. It's not really a distro on its own.

Hyprland might change. Other apps that are installed or even compiled might go stale or change. The chaotic-aur in use might change or need replacing. Arch or upstream packages might make changes causing issues eg some recent issue with a session manager that broke a lot of installs.

Etc.
