Weird, I could have swore it was in there. We should add the 
'metadata_version' key.

In the interim you can detect when it's a 1.2 because it has specific 
fields , by loading the metadata in a packaging.metadata.Metadata instance
and ask it to detect the version.

You can try with http://pypi.python.org/pypi/gitbuster/

(notice the UI that lists the dependencies)

Also, as discussed with Richard we said we would publish 'setup.cfg' in 
PyPI. So that will be another way
