Thank you, Rupi Dhindsa, for pointing out that the term 'normal user' is not particular helpful in terms who might be a group interested in testing pre-release Gutenberg versions. It's definitely for user who know and have permissions to install plugins, need to prepare themselves and their sites to be compatible with upcoming releases or have a genuine interest in assist in testing new features, but are non-developers. There are other reasons. It's still a fairly large group of WordPress users that can benefit from the Gutenberg Nightly plugin.
