Typhoon/Rafale should be the best in game and instead they crap on Typhoon, buff the Rafale and as you said Typhoon will find miraculous buffs/reports actioned when the Su-35 and F-15EX are added.
EF was made for transonic speeds, the plane was not made for slow speeds and high AoA. In reality, having high alpha and maneuverability at slow speeds is not that important. That explains the AoA limit on the EF. Although even here there has been a drift towards 30 AoA due to the aerodynamic kit which of yet nobody wants.
Difference is that for the rafale 2 things corroborate the existence of such a system
the plane had a full override system used to get out of flat spin (would be nice if it worked in game lol)
the plane has performed 100º AOA maneuvers, at -40kt, without loss of control.
Those 2 show that the plane has its ways to override the usual AOA limiter completely
And the big problem with both the rafale and EFT is that the flat spin gets worse as time goes. The rafale hits insane rotational speed, and it’s impossible to get out of it with split throttle and good inputs. I tried for a very long time
But the EF can’t have the ability to turn of its fbw because it is an unstable airframe and it would just get out of control if you deactivate the fbw.
Causing damages in the millions.
I think you misunderstand something. The button is to override the limits (G-Force, AoA, etc.) of the FBW and not deactivating the FBW completly. These limits are there to keep the flight envelope inside the given parameters even if the airframe could withstand more (at the cost of airframe lifetime). So with this button you trade airframe lifetime for increased manouverability.
Deactivation of the FBW is impossible in modern aircraft, except the avionics fails with all its redundancies but then you would be lost either way.
All I have seen until know it that the “button” recovers you from any departure from flight irl and doesn’t override any g-limits
(most planes are limited to 9g I don’t think it is reasonable to assume that it overrides the g limit to anything higher than that)
On top of that from what I have heard in pilot interviews the EF recovers automatically and does not need any pilot input
