From the package-index-api:
3. Omitting the /version part of a project page's URL (but keeping the
trailing /) should result in a page that is either:
a) The single active version of that project, as though the version had
been explicitly included, OR
b) A page with links to all of the active version pages for that
project.
So base/project is not a legitimate resource and should be re-written to
include the trailing slash. Will do this with a redirect provided that:
- On its own base/project is not found in the project-index re-write map
- base/project is found in the project-index re-write map
