In reply to Joen.

I think some of our reactions are tied to the apparent speed with which the plugin is evolving. It's at version 0.8 and it's been incremented quickly which communicates it's much further along than might actually be the case.

The other thing is we keep seeing new blocks being tossed in and it doesn't feel like the core experience is smooth yet. As for gathering feedback... you HAVE to gather it from endusers of various stripes, not developers or other technical folks. None of my clients are technical. They all use WP to run sites and they need a core editing experience that's intuitive, easy to pick up and that gets out of the way. Most of them don't use a lot of different things - they mostly add in text, format it and place images.

Finally, it doesn't feel like Gutenberg has a clear mission for 1.0. Why are you adding layout things like columns? Columns aren't content editing - nail the content creation and editing experience. THEN, perhaps, move to layout. Layout blocks like columns open a huge can of worms - what if a client tries to use the column block on a page controlled by my template that uses CSS Grid to lay out the page?
