FF is not an easy toggle at all. It dramatically changes difficutly because enemy statistics might be scaled to no FF. Adding a toggle for FF might screw-up the difficutly and make a hard balanced for no FF harder than a nightmare balanced for FF.
That's why they should hide the toggle in an .ini file so users can't change it without knowing that they risk breaking the game.
The Total War series has often been good for this. For example, in Medieval II: Total War, there was an .ini file that controlled all manner of variables - which factions were playable, what unit costs were, and how long each turn was. There was basically a line that said:
Turn length = 2
And that value, 2, was measured in years. The player could edit it manually and replace that two with any rational number and the game would still work, but the balance would be greatly affected. If he changed it to read:
Turn length = 0.5
that would mean that each year would include 2 turns (which also meant that half of the turns happened in the winter, which would never occur using the default setting). The result of that change was that technological advancements - which were tied to calendar years - would happen much more slowly relative to gameplay turns, so by the time gunpowder was intriduced each faction would already have fully upgraded pre-gunpowder buildings and units, and much larger armies. And a less fun game, in my opinion, but at least it was something the player was easily able to fiddle with if he wanted to try some things out.
