As I've noted multiple times here on HN, I don't disagree with this.
But the question is not about whether it is a more accurate and honest term. It is about people complying in advance with the illegal/extra-legal renaming of a federal agency by a president who does not have the right or authority to do so.
If we were talking about Congress voting to rename the DoD as the DoW, I'd have nothing to say on the matter that differed from your observation.
