There's no point in feedback since you can't go back in time to fix those issues. You should already be able to guess from looking at the profiles of students who got in and those that didn't.
Maybe a college tells me that a particular type of extra-curricular wasn’t valued as highly as I thought it was and I elect to pursue something different in undergrad (I wouldn’t recommend this but to each their own). The feedback would also provide relevant data points to future applicants if chosen to be shared.
There are plenty of examples of students who are accepted/rejected to schools which you wouldn’t expect.
