I would argue the issue was not checking the coverage of new code vs what was being tested.

  The OP is pointing out that what "the issue" is depends on whether you want high confidence that your code has few bugs, or you want certainty that your code contains no bugs.

    > you want certainty that your code contains no bugs Well, everyone would want that, but it's not possible. Formal verification comes nowhere close to promising that, especially not on a large project. I'm pretty sure OpenSSL is larger than any formally verified software to date (perhaps CompCert is larger?).
