Code management, code versioning and code fixing are all hard problems. You can't in all cases put a simple tool/thing in front of it and fix it. Sometimes hard things are just that, hard.

Also; git isn't meant for your "average" use case. People sometimes attempt to get content writers or other non-technical skills into git. It never works. There are far better tools purpose built for those use cases.

Developers want tools that work, git works. Why would we try to make it better?
