> For example, the structure of EEOC Title VII inquisitions pressures companies to search extra hard to hire diverse candidates from a fixed size pipeline (the only way to make this work is to relax qualification requirements while pretending qualification requirements aren't relaxed, and maybe to fire any employees who fail to play along), but they can only go so far before they run up against the letter of the law which prohibits them from, say, openly firing people for their race.

This assumes worker pipelines are fixed which, practically, they aren't. You can increase flows to the pipeline by increasing outreach or incentivizing attainable qualifications. You can also seek trainees rather than day 1 contributors, which admittedly _is_ "relax[ing] qualification requirements" but has the trade-off of providing more purpose-fit employees when they do start contributing.
