Sorry, I should have mentioned I was being sarcastic, I absolutely hate the "not necessary" argument and am a huge fan of FF characters in KH, especially Leon, I agree with everything you saidI
It's incredibly necessary for the FF characters. The big-wigged assholes who destroyed their world and ruined their lives are back in their positions of power without a single fuss. They have free reign to do whatever the hell they want again (e.g. abduct more children) and the people are just okay with that. I can buy that the people were never informed of who the culprits were. I can buy that the FF characters weren't immediately aware that Ansem and his apprentices returned. However, I can't buy how easily Leon&co. accepted them back given their knowledge.
The Restoration Committee (essentially a neighborhood watch group on steroids) VOLUNTEERED to tend to the survivors and restore their world. And now they're just okay with serving the very same ivory-tower assholes while giving even less of a shit than a simple "eh, whatever."
I'm calling upon the sacred gods of bullshit if it's revealed that no form of civil unrest occurred during that 1 year time skip.
