Tbf that was always kinda the point. It was a coined to mock the creation of White House office positions that had no legislation justifying it’s existence, as opposed to the Federal Departments.
If the office was created, and position filled undemocratically, then calling that office holder a tsar makes some sense, if clearly hyperbolic.
Obviously, this one is a Senate approved appointment, so the point is diluted.
Happens to the best of us.
