A good way would have been to add #pubky which is git native identity and signatures, using ED25519 keys, tied to nostr identity. Another good system would be NIP-98 to log in to say gitea/gogs/gitlab. You also get free SSH, and commits, out of the box, for free. Key is to let each tool do its thing and expand the network effects. Then with a few tweaks you get enormous new functionalities. Git does come with a very basic server, yes, I've used it a few times, but it'll require a lot of support, and lacks alot of features. We were discussing this problem and using ngit for resilience with the Agentic folks today. I think in future there will be a an offering for humans (high support) and one for agents (low support).
