I'm also not too fond of simplifying too much the usage of git; git is a very powerful but also hard to learn tool, and most "utilities" that try to make its usage easier give *very* bad practices to their users. And if we want our users to be co-developers of Godot to some extent, they need to learn good practices :)
But if there were a strong wish for in-engine VCS support, it should likely be done with a simpler tool than git. Maybe something like fossil.
