It allows retaining the version number in the downloaded artifact's name when the version to be downloaded is dynamically determined ('latest').
So far, the behavior was to overwrite the version string in the artifact name with 'latest' which leaves no trace of what version the downloaded artifact has. E.g., you cannot use this information for further processing like transferring it to an RPM that is built from the artifact.
