I've been thinking about this a lot lately as well but from a different vantage point. I put together an "ast-crdt" project combining Abstract Syntax Tree and Conflict-free Replicated Data Types) which allows multiple agents to effectively merge multiple code changes. The initial thought was to answer the question "what would it look like to allow modifications to the same code project by multiple agents in a safe way without relying on git semantics (and the inevitable merge conflicts)?" It also touches on the idea of "what if humans are removed entirely from the commit-PR-merge workflow?" All of this to say git-centric forges as we think about them today would start to look very different.
