The vast majority of WordPress users have never tried Gutenberg, and probably know nothing about it.

When they update to 5.0, they're going to be presented with an unfamiliar editing screen that changes the way they write content.

That's going to cause a massive blowback and influx of support requests. We've already seen the beginning of this in the .org forums.

Yes, the Classic Editor plugin can be installed - but there will still be additional support requests from people who want to use Gutenberg, but are struggling with it.

Even if 5.0 is deemed to be "ready" for release in late November, it shouldn't be released until January. If it is released over the Holiday season, send your thoughts and prayers to the people working in WordPress support.
