My guess is they'll tend more to let the judges decide, because Congress is, in fact, timid, lazy, phony, tiny, and small.
It's complicated, but it's a good thing because it restores accountability to the political sphere. No one elects the agencies. But that will cut both ways, seeing how politicized the judiciary has become.
It's also a BFD. The New York Times is in a panic over it.

(of the U.S. Constitution) anticipated, and the executive branch is left
to do far more by deciding controversial issues via regulatory fiat."
More.
