Sure enough, a report on Berkeley's diversity initiative—recently publicized by Jerry Coyne and John Cochrane—shows that eight different departments affiliated with the life sciences used a diversity rubric to weed out applicants for positions. This was the first step: In one example, of a pool of 894 candidates was narrowed down to 214 based solely on how convincing their plans to spread diversity were. - https://reason.com/2020/02/03/university-of-california-diver...
I'll let you decide if using this criterion as the first step, that disqualifies 76% of candidates, is a "token gesture that takes 0.05% of your time".
Regardless of how arbitrary you claim the filtering is, the effect is the same - it makes commitment to diversity the most important, primary criterion.
