Well as I said this helps only if the package has 100% test coverage,
such that the developer is sure to exercise all code paths when he/she
runs the test suite with warnings explicitly enabled.

Besides, as Yuvgoog pointed out, this would not help the casual hobbyist
programmer (or professional non-programmer, such as a scientist) who
doesn't really have a clue that those warnings exist and are important
to check for.
