I still believe the only explanation for eliminating clear, measurable and quantifiable metrics for university admissions is because universities are looking for discrete ways to continue discriminatory tactics against Asians and to a lesser extent, whites. This is not about legacy admissions practices.
"Berkeley diversity statistics show that the enrolled student population at the University of California, Berkeley is composed of individuals who identify as Asian (30.6%), White (25.4%), Hispanic or Latino (16.3%), Two or More Races (5.5%), Black or African American (2.42%), American Indian or Alaska Native (0.139%), Native Hawaiian or Other Pacific Islanders (0.132%), and Other Pacific Islanders (0.132%)."
