I don't think we read the same article. Here's the first statement...
The Trump administration has drafted plans to strip key authorities from the Bureau of Alcohol, Tobacco, Firearms and Explosives
Unless my reading comprehension is gone, this article is about striping power from government rather than creating a new agency. You can complain that Trump isn't going far enough, but I don't understand your point.
Well, I think you are failing to see the big picture. It sounds to meek like they are an empowering an agency to go after guns full time and with full force.
