Possibly, but I'm not sure it does/can. From my limited understanding,
the version number is determined by the git tag (for stable packages - I
think the date is used for unstable). This is as it should be as it
should be the package maintainer who controls the version number, not
the packaging service (especially for maintainers who use semantic
versioning where the version number actually conveys information about
the package).

At the end of the day, this is essentially a supply chain problem. To
really have confidence, you need confidence in the whole supply chain,
not just the distribution centre.

Personally, I wish both GNU and Melpa had adopted a push mechanism for
package release. Something similar to npmjs.com where the package
author/maintainer would submit a signed package (publish) to the
repository. This would make it producers of the package code we trust,
not the distribution center (repository). Main downside with that
approach is you would also need a reliable mechanism for retrieving the
public keys (there would be a lot more of them to manage). I also think
this would be a model that is a lot easier to scale (something I think
GNU will have problems with under their current model.
