This is an easily-solved problem. And in case one slips through, versions are easy to delete in Grace.
Don't get me wrong, many concepts are great (such as the watch/auto rebase). But I still would base everything on top of git. Call it the network effect or whatever, but every nice concept you promote could be done with a git wrapper. Version repos are a solved problem, and git is so much a de facto standard that fighting it will be ... interesting.
It's so 2024 to not actually engineer things but say (only say) "we tackle it with some ML model". I have goosebumps from a though that VCS would require GB data file for the model or require (let be honest here, 99% more possible, nobody creates own models) an online chatgpt access.
