Re-designing a modern source control system for open source projects, you need to consider millions of developers have coding agents running on their computer and/or have Claude Code/Google/OpenAI coding agent accounts. And evidence from the Linux repo and many other GitHub repos, the open source projects are overflowing from coding agent submitted bug reports. If I was accepting a bug report and/or patch, I would want to know the stated problem and reasons why it's a problem, the desired state or fix and reasons why it's preferred, and if a patch is supplied, I would want verifiable proof of provenance: the signed session from the coding agent, including the prompts used to generate it paired with the changed code. This way open source maintenance can become truly decentralized.
