I've been recommending my clients avoid using it for minimum 6 months post "release" regardless of accessibility.

Gutenberg has been changing constantly. When it's "released" it should only be released as a final version to developers, meaning they're no longer changing it, before being released to the public.

I've known a few people who've developed Gutenberg compatible plugins, only to have it break 2 weeks later when an "update" arrived. "Update" meaning "it's been redone entirely different".

It's been noted elsewhere here - use the official "classic editor". Gutenberg offers ZERO benefits. It's simply a different way of accomplising the same tasks.
