sdists do have egg-info::

 $ svn co http://svn.zope.org/repos/main/zope.interface/trunk xxx
 ...
 $ cd xxx
 $ /path/to/python setup.py sdist
 ...
 $ tar tzf dist/zope.interface-4.0.2dev.tar.gz | grep requires
 zope.interface-4.0.2dev/src/zope.interface.egg-info/requires.txt

Now, that doesn't mean that the contents of requires.txt might not be
different when installed on a different platform or Python version, but
for the vast majority of projects (/me waves hands), this works just fine.
