No, I wasn't talking about packages.python.org at all, but about
docs.python.org. For packages.python.org, it's up to the individual
package to support versioned documentation.

For packages that have only one (visible) release, the whole discussion
of whether meta-data are per-package or per-release is pointless,
anyway. This is the simple case, and we can resolve it either way.

That's completely up to you. If the new zip file contains the
documentation of all versions, you get multi-versioned documentation.
See, for example,

That's not true. If there are multiple visible releases, no release
is singled out.

That's because distribute has only one visible version. Just unhide
one of the older releases.

And I'm fine with that, except that I believe that a documentation URL
(if supported) probably should be per release.
