I don't mean that any of your QC tests were redundant, what I mean is
that QC runs your tests with redundant values.

I don't think there is much benefit in having the tests if we aren't
going to run them. People making changes to the library will probably
forget to check that they pass (or not know that they exist), and the
tests will probably bitrot due to changes in other libraries etc.
