Current solution to handle pyproject.toml python projects is not working at this moment.

Previously to FL-8681 just providing DISTUTILS_USE_SETUPTOOLS=pyproject.toml used pyproject2setuppy instead of setup.py, but with current solution (setting this var to autostub), creates a generic setup.py that will try to discover modules.

That solution would require to manually install modules or remove i.e. the test before installing and will require lot of works to handle things like setup.py entry points.

Maybe I am missing something, but I can't find an easy way to just build the package as the pyproject.toml specifies.
