[Distutils] PEP440: foo-X.Y.Z does not satisfy "foo>X.Y"?

but look at this (using setuptools 8)

>>> '1.7.dev1' in pkg_resources.Requirement.parse('foo>=1.7')
False
>>> '1.7.dev1' in pkg_resources.Requirement.parse('foo<=1.7')
True

Only the exclusive ordering section speaks of the "!= V.*" bit.
The inclusive section just talks of zero padding and relative ordering.

The packaging implementation that underlies all this seems to bear this out
as well:

inclusive:

exclusive:
