> I think the big issue is that programmers aren't taught to properly leverage git in this holistic way

You are assuming here that all programmers even "do" git. A lot don't. A whole lot of them. I worked with some companies that would have some horrible horrible version control system only and I just wanted to cry. Sure, git has its warts, but once you get it, it's a tool that can be _incredibly_ productive. I hate having good tools taken away.
