Those two are orthogonal.
The index itself is just a bag of things and, as such, one that's very
well suited to publish data, since it can easily be exposed in form
of static files, which can be put on a CDNs or mirrored using
It's easy to add the metadata file to that index for tools to
pick up - in addition to the other data exposed on the index
pages and perfectly backwards compatible.
As mentioned before, I think we should start publishing the
existing metadata stored in the PyPI database on those
index pages as PKG-INFO files, so that tools can easily
access the data without having to go through XML-RPC.
