It seems like this kind of problems occur mostly within some specific areas, meanwhile OP seems to suggest that this kind of review should be applied for everything.
From a practical business perspective, performing a diversity and inclusiveness review is a risk management activity.
It doesn't really matter if the business strongly supports or opposes a particular set of diversity and inclusiveness goals from a fiduciary perspective, but it sure does matter if the business keeps losing money or missing targets because it is embroiled in scandals, paying out settlements to staff that have suffered discrimination, or being hauled in front of regulators to air their dirty laundry.
One would hope that being a decent place to work, and treating people fairly would be enough of an incentive, but for everyone else, there are risk management processes designed to have repeatable processes to identify business risks, escalate them to leadership, and presumably either accept the risk, or steer the project towards a solution that has a more acceptable risk profile.
Not every kind of review is applicable for every single launch, but diversity and inclusion is applicable to more than just AI (in general, I don't know what the review process or requirements are for D&I)
Sounds unnecessary. You just roll it into the D&I review. There is such a thing as a D&I review that comes down to a couple paragraphs on how this product has no features that are relevant for diversity or inclusiveness.
But Google added the review because they found that, in general, the average software engineer does not have the background or technical experience to make an educated guess on that topic.
