NEWS FLASH. The term backdoor prohibition is now obsolete. They now have the power to start prohibiting stuff right through the front door.
And they will.
You will no doubt note that this has nothing to do with "keeping and bearing."
But then again, Form 4473 has nothing to do with gun registration.
Let us hope that this one is a flash in the pan... A gun term, of course.
