If you elaborate on specific use cases that will be useful.

git as a DB I think is not that useful. I'd guess in most cases you'd be better off with sqlite.

regarding the collaboration use-case I think it's also not that interesting outside of the usual code stuff.

Maybe some git-inspired features can be made such as diffs or merge requests but I don't think you'd neccessarily need the real git for that.
