The name of that Department was chosen to be aspirational, to encourage it to try to keep within its Constitutional guardrails, to keep it focused on the right mission.

Sure, it often didn't live up to its aspirations and a lot of the fence posts of those Constitutional guardrails got moved, but wearing those aspirations on its sleeve left some room for people to challenge it and openly criticize it by reminding the Department of its guardrails and its mission.

The name change is disrespectful to the Constitution, if not terrifying for other reasons.
