The git protocol is more complex and harder to scale. It's especially wasteful if people are going to redownload all packages every time their amnesiac CI runs.

Single-file archives are much easier to distribute.

Digests and signatures have standard algorithms, not unique to git. Key/identity management is the hard part, but git doesn't solve it for you (if you don't confuse git with GitHub).

git bundles exist to solve the single-file caching and distribution problems

Going crazy: we cold also adopt the container registry api for distributing gems, similar to how helm charts are also distributed nower days.
