Since you asked, I have a problem with the rule 7 when applying
it to packages like numpy.distutils and numpy.f2py, for instance.
Do you realize that there exists bugs/features for which unittests cannot
be written in principle? An example: say, a compiler vendor changes
a flag of the new version of the compiler so that numpy.distutils
is not able to detect the compiler or it uses wrong flags for the
new compiler when compiling sources. Often, the required fix
is trivial to find and apply, also just reading the code one can
easily verify that the patch does not break anything. However, to
write a unittest covering such a change would mean that one needs
to ship also the corresponding compiler to the unittest directory.
This is nonsense, of course. I can find other similar examples
that have needed attention and changes to numpy.distutils and
numpy.f2py in past and I know that few are coming up.
