Historically, it's been unusual for NFL to originate a provision and for it then to go directly to Fed without passing thru NCAA. I can think of just one general example: the wording and details are a little different, but the most recent rule allowing forward passes from anywhere in & behind the neutral zone started with NFL and spread to Fed before NCAA. When the forward pass had first been legalized that was the rule, but within a few years restricted to originating at least 5 yards behind the NZ, and that's the way it was when NFL & Fed started writing their own rules, so in a sense NFL can be said to have originated ("Re-originated"?) it.
The differential face mask penalties IIRC began with NCAA, but I don't remember whether Fed or NFL adopted them next. So this new change is another case of NFL's "re"-originating a rule provision.
