The Ruby ecosystem is already decentralised in that there is no single source of truth for published gems. You can pull the source from any software forge that uses git, you can point to any self hosted gem server or use something like Artifactory or GitHub package registry. You can vendor the code if you want.

This entire post is practically the case in point, except I’m not clear on how they got real time sync with RubyGems and if any other competitor would have the same capability.

To use Astral and uv as an example, they would have to fork PyPI and maintain all the infra for that and not just the tool that manages the dependencies.
