Gutenberg isn't about WordPress (dot) org. It is trying to address a problem that didn't exist within that realm. We have excellent page-builder options. Gutenberg is about Automattic competing with SquareSpace, Wix, etc.

I feel sorry for theme devs and even site designers/developers or site owners who now have to deal with this. I'm glad I exited site designer/developer space, so now only have to worry about this mess as a site(s) owner.
