It may not matter a hill of beans but I’m glad to know we have several copies. I just ask myself who had an interest in blurring the lines of natural born citizen and naturalized citizen because that in essence is what has been done. In the first case an assertion that the Statutes of the Naturalization act are not to be taken as fulfilling the constitutional definition, on the other hand we now have a title and content stating that a Citizen created by these Naturalization Statutes is not to be considered a naturalized citizen.
Just look at the breadth of entities blurring the definition. All are part of managing the transition of the US into a post-national global society. History has to be buried, not totally, just enough to maintain sufficient public belief in the "new.". FAM and CRS will be cited as primary authorities, and I would guess 95-99% of the population is none the wiser.
The “not to be considered a naturalized citizen” has been in the FAM since at least 2007. Here is the archived version:

Previously the “not naturalized” section was 7 FAM 1131.6-3 Not Citizens by “Naturalization” but when they removed the part about eligibility to be President, they renumbered it.
