`distutils_enable_tests setup.py` is deprecated and going to be removed from the eclass (following upstream deprecation of the same thing). Please switch to some other unittest provider, e.g. `unittest` or `pytest`.
My hope is that they finish the Meson port soon. Eli has offered to help them get it over the line with review if they need it.
If it becomes urgent (one of the last consumers), I can temporarily remove tests.
