Because the distribution name is not the packages names.
See for instance the Paste project : PasteScript, Paste, PasteDeploy.

When would distribute.resources need version comparisons if its sole
role is to provide query APIs
for installed packages ? (pre-PEP 376, then PEP 376-compliant)

pakage_index would be included in distribute.installer, and we could probably
add simpler APIs to use it to drive a download

So, like a subpart of package_index ? this is a nice idea, so tools
like yolk or z3c.pypimirror could browse pypi index with it,

It could also have a full xmlrpc client implementation for PyPI xml-rpc APIs,
