@narendraR asked on Slack if we could revert/undo/uninstall a recipe after it has been installed.
It doesn't look like there has been much discussion on the subject. A user could uninstall all the things the recipe installed manually. But we also have the idea of config snapshots that may lead to having a way to "undoing" a recipe installation.
