You _never_ have bugs that slip through the test suite? That is extremely impressive / borderline impossible. Even highly tested gold-standard projects like SQLite see bugs in production.

And once you find a regression that wasn't covered by your test suite, the fastest way to find where it originated is often git bisect.

Bugs that slip through the test suite and it's important to trace the origin and it requires building more than a couple best-guess versions to find it. And even then, if it wastes an hour or two once in a blue moon that's not a big motivator for workflow changes.

You're skeptical of a far stronger claim than the one they actually made.

Performance regressions often match all of those constraints, at least in an active project.
