Just because they’re adding an F-4 and MiG-21 doesn’t mean they can’t go back and fill things in later.

Right.

F-84F FJ-1 A-4 A-7 Yak-25 (both of them) Scimitar Etendard Mystere IV Sagitario > Ariete AMX Gnat Swift up until this week

Just off the top of my head. Those are all aircraft that could have been added after they repealed the 1952 date restriction (some before it) and they still aren't in. WAY before all of this. And now after introducing afterburners and supersonics...

F3H F4D F-11 F-89 F-94 F-88/101 F-104 MiG-17F Su-7 Super Etendard

Once again just off the top of my head.

Now I'm not crazy enough to think they can do all of these, but they have vastly ignored anything but top tier historically. I mean just look at the Italian and French trees in their entirety... and we're only now getting another Reggiane. I have my doubts.
