They still do those. However in the years before remote learning and increasingly after, schools started buying services like blackboard or canvas. These are academic websites that manage homework assignments, deadlines, store the syllabus, announcements, etc for each class where the teacher bothers to use the system (most of them at least have a syllabus if nothing else posted). They also allow assignment submissions, even timed testing environments where the browser is locked down. They also link with turnitin to check submissions for plagiarism. Courses that have grown reliant on these third party tools will have to simply turn the clock back to 2010 or so and go back to in person assignments. I wouldn't be surprised if it got to the point of otherwise fully remote classes booking a room on campus 3x a semester to conduct exams, because a paper exam seems so much simpler than fighting an arms race with chatgpt and electronic submissions. This might not actually hurt companies like blackboard or canvas that much, because universities are like these big cows where once they have an institutional license they will probably maintain it forever, even if they are also buying the competing product (typical to pay for microsoft business and google cloud services both even though they are entirely redundant for example).
