You are thinking about this wrong.
If it is so easy and quick to teach people how to use git, then why aren't colleges doing it!?!?
Learning how to use common software engineer tools is a low effort, high reward situation. All they have to do is spend a day on it, and they have now made their students significantly more valuable.
Educational institutions that do not even bother to spend such a small amount of time, in order to make their students much more valuable, are making a huge mistake.
I can confirm that there are theory-focused professors at a particular state university that don't understand version control or have any experience with it. It's not that they don't see any value in it, they just don't have any experience with it to pass on to students.
Some of them actually do.
When I was in school I'm glad I went out of my way to take all the math-heavy and theoretical classes I could, and no classes like "modern web design" or "software engineering project". Learning basic programming is trivial and something I literally get paid to do (so long as I learn at a decent rate) while all the knowledge I have about math and theory is a lot harder to learn outside of an academic setting and is a force multiplier on most things I do for work.
