I read both blog posts advocating for a delay, but I don't think more time will fix the underlying problems with Gutenberg.

Javascript-heavy writing interfaces tend to have a certain level of jank and wobble that can't fully be fixed.

Look at the help forum for Squarespace. Editor issues abound, and their project is several years old.

With that said, if Gutenberg won't break sites, then it's ship-worthy.
