I bet you that a Nostr-based versioning system could work really well. It may not be exactly like git, but something similar could possibly work.

 It has to be atleast fully git compatible. (Like podman is to docker). Mastering git takes a lifetime, nobody wants to learn a whole new version management tool. 

 I don't pretend to know git, so I don't know how feasible it would be to replicate via Nostr
