I'd argue that linux distros have this power, too, and they haven't either (unless you use a snap, which has compatibility and performance issues).

If you uninstall a .deb or .rpm or AppImage, the files you wrote into XDG_CONFIG_HOME (defaults to ~/.config) won't magically get cleaned up.

I'd love to be wrong here, BTW! I've had several PhotoStructure users try to reset their configuration by uninstall/reinstall, but that just removes the files in the installer, it doesn't do anything to files in user directories (and I'd be really surprised if that was ever a thing). Can you imagine the havoc from `apt remove vscode` and having it remove user's keybindings, extensions, and anything else?
