I just played around with this for an hour…and it does not belong with WP.
WordPress started out as a blogging platform. People got behind it and it became something much more than blogging. Don’t try to compete with wix and squarespace, WP is so much better than that. Please do not make this mandatory editor. If you are hellbent on destroying the editing process, at least allow us to uncheck the “Gutenberg” option in settings so that can keep on being productive. There are so many free visual composers that do this better.
The users are what made WP such a success. Listen to the users. Gutenberg has no place here.
