That's exactly what this may do. The ATF in theory can't just up and decide what to ban without congress making a law. Turning law abiding citizens into felons overnight. Bumpstock ban? That's gone in theory. FRT trigger? Braces? ATF is going to quickly realize they can't just make shit up on the fly if it's not a law.
But based on Egbert and Vega, there's now precedent for federal agents to perform warrantless raids, seizures, and arrests, without reading Miranda warnings, with no legal consequences.
