I agree, but am pleased to see it.
From a personal perspective, every hobby or interest I have exposes some other federal agency that's hostile toward it, and hated by that community for going well beyond their statutory authority.
Speaking more generally... I think severely curtailing the non-statutory authority of federal agencies is just about the only path toward keeping our federal system in the long run. Most of this country (by area, not population) is increasingly resentful of the federal government's actions, and their ability to enforce the law is decaying over time.
I think we'll see the Chevron Doctrine significantly limited, if not completely overturned. There are several firearms cases working their way through the courts now that would be well-suited for that. If it's done via another case, those will likely be remanded and reversed by the appellate to avoid setting more precedent specific to firearms.
