In reply to Leo.

I was the one who wrote that comment. I really appreciate seeing a clearer example of how a workflow like that would work.

I still see big problems with letting users change design elements (i.e. image sizes) and reordering blocks - I hope there is a plan for some sort of block-locking ability or a way of turning off certain block features. But the more I read about Gutenberg I think I'm starting to see the vision - this really does have the capacity to radically change WordPress, which just underscores how much it needs to be done right.
