Very good feedback, this.
I think there would be some options for a combination between necessary and sufficient conditions. My sense is that a good combination would be between legitimacy, regency, occupation, harsh treatment, different culture/religion and crucially "autonomy reduced". That should really be the moment when the local nobility says "wait a second, when you integrated us peacefully, you didn't tell us you'd take away our ancient rights and privileges - to arms!".
Basically I'd love this concept as a player to make it more interesting, and varied, to play some of the bigger countries. It would be cool to have to factor all of that in when you decide whether to eat a vassal, convert provinces, reduce autonomy etc.
