Ah now I understand the purpose. I only use it for my (personal) dotfiles, which as a term is ambiguous at best, but in my case I mean config files. That was how I essentially misread your title. Obviously all those files are owned by my user, and most live in ~/.config or similar locations beneath my home directory. Things like application preferences, basically.
Obviously your tool also works for this, but I now understand it's more meant for system wide config files.
