In the Java world, Maven has a "publish" step. Published artifacts (groups of files) are immutable, so publish == finalize.

  That’s exactly how individual artifacts are (and were) on PyPI. This change isn’t to artifact immutability, it’s to releases (collections of artifacts)

    Yeah, I think that's the difference. In Maven, the entire set of files which compose a release is immutable. You can't add to or remove from the set of files once you've published. You have to release a new version if you want to add anything.

      Interesting. I’ve only used Maven-format repos once or twice and always via somebody’s preexisting CI tooling. Is there essentially a “draft” release that you can edit repeatedly before hitting “publish”? Is that draft release visible externally as a pre-release, or only to the author?

        There is indeed a "draft" release (I think they call it a "deployment"), but AFAIK your choice is then to either publish it or delete it. If you review it and it looks good, you publish it and can't change it thereafter (no changes to files, no adding new files, no removing existing files). If, however, you need to change something in the deployment before publishing it, you have to delete the deployment and create + upload a new "draft" release / deployment (can be same version number, since the previous "draft" wasn't published). AFAIK these "draft" releases are visible only to the author.
