Excuse me for being a dim-wit but isn't Gutenberg in core? I see that it is also still in the Plugins repository. So can someone please explain how this works - 1. Will the plugin override core? 2. What happens if I deactivate v5.7+ of the plugin before core is updated? 3. When will core be updated to 5.7? Thanks in advance for answering my outrageous (...ly obvious) questions!
