I've been using it and, it works fine. It's not perfect but it is NOT light years away. Most people could start using it now and get use to the workflow and a few changes. IMHO it's going to be a GREAT update to the old Editor. The UI is quite intuitive and, I'm REALLY looking forward to see what the page builders, plugin developers and theme authors do with it! My experiences with Gutenberg 2.50 have been positive so I'm using it now - not waiting for it to be perfect.
