I agree that it's a bad goal, in terms of how it being a goal corrupts the value itself. Like in Goodhart's law, "When a measure becomes a target, it ceases to be a good measure". But managing a larger entity cannot realistically be done via values, I think. Different people have different interpretations of the same values, and not sharing the values 100% in the first place, so, the values will need to be formulated into more tangible things, like goals, limits, directives, laws, ect. Will not be ever perfect, but I doubt that we have better tools to achieve it.
There's also the Martin Luther King thing "...will not be judged by the color of their skin but by the content of their character." A lot of DEI hiring seems to be about fashionable skin colours.
