There's definitely a need for this, but the underlying reason there's a need for this is so beyond me. I've worked with a lot of Software Engineers over the years, even at FAANG, that didn't have a good technical understanding of git (basically, your repo is a tree structure, most commands are just about manipulating that tree in some way). I mean, just spend the hour to go through a git tutorial. There's so many great ones like the interactive one that shows the tree as you go through the levels. It's your profession. Also, I think another layer on top of Git as this seems to propose won't fix it -- once something non-obvious happens, these people continue to be stuck.
