I run an agency that builds WordPress websites, and have been wondering about what to do about all of this. I'm concerned about the future of wordpress.org and have been looking around at alternatives. This seemed sort-of interesting initially but, without wishing to be uncharitable, this looks like a nostalgia project because the Gutenberg editor, while initially quite tricky to wrangle for developers due to breaking changes, has been a real step forward for content editors. It's mostly stable now, so the decision to remove it from this makes it a non-starter for me.
