Ok, that makes sense.

I mostly use the distutils sources as reference, and the
DistributionMetadata class generates provides metadata as documented
in the corresponding PEP if the requires attribute is not empty.
Does it make sense to generate PKG-INFO with the requires field which
value would be taken from the install_requires ? I am using sphinx as
my main test for the conversion now, and I noticed that setuptools
does not generate a PKG-INFO with those data (v1.0 instead of v1.1 as
I would have expected).

Will those arguments be added to distutils as well ? Or should I
consider those arguments only when I detect
distribute/setuptools-based setup.py ?
