You are right. Some things go way back, like Harvard’s antisemitic institution of a “character” rating in the '20s, in order to exclude those pesky smart Jewish boys who were outcompeting the good old WASP boys. That heavily weighted “Personal” rating is being used to the same effect even now, although now it is the Asians who (at least as of the 2018 lawsuit) are being dinged. https://www.nytimes.com/2018/06/15/us/harvard-asian-enrollment-applicants.html
This is why I say it may get more interesting, depending upon how the Supreme Court rules in June 2023.
