Answer 1

Perhaps this is obvious, but, for reproducibility, developers should never overwrite artifacts, they should be new versions.

This also applies to upstream repositories. If you download Apache-commons version 1.2.3, you should really never download it again. Fixes come from latter versions, not applied to existing versions.
