I don't get it. Because they haven't cut a new arbitrary version number, we're denying it got done (in their perspective) and being used in a massive product already?

If you're being pedantic, no it's not "done," but nothing ever is.

It's not "done" if it's not stable and released. It's being canary tested by Claude Code users essentially but it's still being heavily worked on with tons of $ being poured into it and there's still no sign of them considering it stable and ready to go. That's the point of the article.

One single product, AFAIK, and one ladden with bugs and issue too.
