NumPy pytest testing is NumPy specific and not used downstream like our
nose testing framework was, so I don't see why that should affect other
projects. What motivates this question is that the new version of pytest
released yesterday raises warnings for non-registered markers,
`pytest.mark.slow` in particular, and that was causing CI failures. The
easiest way to register a mark is using `pytest.ini`, but we currently
don't include that in released wheels, only in source releases.
