The university could even setup their own private self-hosted Gitlab and use it as part of assignment submission.

10 years ago, my no-name college had a CS degree that required us all to take a "Software Engineering" course that covered the fundamentals needed once you graduated, including Git. We did group-style large coding projects where teams had to submit their GitHub repo at the end.

The prof was able to review who committed what and then hammered us on good commit messages, clean coding style, testing, etc.. I feel that a large part of my career success was due to the early start I had from that course.
