I only skimmed through the website, but it looks like it only does dotfiles. So I'd need to maintain a separate script to keep my packages in sync. And a script with install commands wouldn't be enough - maybe I decided to stop using abcxyz, I'd like for the script to remove it. Versioning between the package and the dotfile can also sometimes be an issue.

Yes, chezmoi is for user configuration. System configuration is a drastically different domain. Personally, I manage that with Ansible.
