I’ve activated the Gutenberg Editor in WordPress. I’ll be able to switch between it and the Classic Editor (which I prefer), but I know that I’ll need to learn it. It’s very similar to Wagtail’s StreamField editor. You create blocks to build your page. It’s supposed to be more flexible and powerful.
I don’t care. It’s very different and, frankly, a pain in the ass to switch. It’s like going from Word 97 to Word 2003 (I don’t remember the exact names). It required learning Word all over again. This is on a smaller scale but it is a big change.
