I realize this plugin is useless right now, since Gutenberg is still a plugin. But is valuable in taking a stand against an imposition that seems unfair, a project that started badly and that stubbornly fails to realize that WordPress is not just a tool for creating content. There are a lot of uses underestimated by the way Gutenberg is being pushed. Not everyone has a blog or a magazine site or a site hosting service company, that benefit from page building blocks. A lot of us have sites that only need a box to enter raw text. Boxes, actually.
Thank you for taking a stand.
