I do not know where you get the idea that developers are excited by Gutenberg. A simple comment that I posed on Facebook produced a vast number of responses from developers, all united in their dislike. I have tried Gutenberg as a plugin for several weeks now, on a couple of my websites. It tends to freeze up the backend. This is probably due to a clash with another plugin, and, when I get chance, I will try to find out which one. But why fix what isn't broken? Gutenberg is an answer for a question that nobody was asking. And it has some considerable problems - Gutenberg's code editor, for example, is just plain text, with none of the helpful tools found in the Classic Editor's code editor.

Wordpress is an open source product. They have the right to do what they like, and I don't have to use it. I will be interested to see if ClassicPress manages to get off the ground as a viable fork.
