In my undergrad engineering department, we see the biggest opportunity for improvement as being in lab sessions, where it's not reliably apparent who is wrong or struggling, and it takes a while to explain to each group what is wrong. We've had some luck feeding from student answers from our lab instructions into structured AI prompts that provide individualized feedback.

But that takes even more time to work on student material, which is not a highly rewarded way to spend one's time. Edit: plus, most of the time my experience is that lower-friction assignments result not in better-spent study time, but in less study time for my course.
