It shows that the CVE fixes were consistent during the last 2.5 years and 14 releases.
Right, yes. But if the transitions from 4.x to 5.0 and 5.x to 6.0 were also shown, we'd be able to see that the bump itself isn't significant, and that this happens after every major version release.
The magnitude of the bump is what's important, and we can't see that without comparing to pre- and post- AI tooling.
Why 5.0 and 6.0, those are ancient. This goes back to 6.9 from May 2024, where Ai usage in the Kernel wasn't a thing until the recent few releases.
That's the whole point.
