And that's where the question of empathy and compassion comes in.

As a random white dude, the "pain" I face by dealing with problems around these name changes is completely minimal and trivial when compared to the emotional pain they cause people in certain groups that actually have a lived experience of oppression.

Regardless, I do agree that if there is crazy scrambling and short timelines to change these names, that's a problem in your org. There should not be reckless urgency to get this done; it should be done just as any other major change should be: with planning and risk assessments. Where I work, we are doing it slowly and with an eye toward not causing downtime. If your org is not doing that, then I agree that you have a valid complaint. But this complaint should be directed at the bad process, not at the work itself.
