I have a feature request for distutil-ng (or maybe it's already
possible but I don't know how).

I have a package that depends on python-dateutil:python-2 for
python2_x and python-dateutil:python-3 for python3_x.
Would it be possible to have virtual targets like "python, python2,
python3, pypi, jithon" ?

Thanks,
