We only insert things into the cache if they have plausible version numbers, so that we don't contaminate the cache with things that were not unique. E.g. ./package might have dozens of installs done for it and build a version of 0.0...and if we built and cached a wheel, we'd end up using the same wheel even if the source has been edited. :param link: The link of the sdist for which this will cache wheels.
