I haven't thought this through at all, but what is problematic about students finding out their admission results before whatever magical date? At first glance, it doesn't seem like the students are worse off (they have more time to plan/act based on their admission result and are free to not look at the information if they don't want it), nor does it seem like the school is better off (I can't think of a good way for them to take advantage of students' uncertainty right now).
