If I understand correctly, the new unrest system is planet-based and each planet will have its own rebels. I think ingame factions should have some mechanics for a larger rebellion, such as taking down the government and establishing a new one with completely new ethics, rather than just liberating a planet. Will you add some new features about this concept? I think the governments in Stellaris are too stable and I really want to see a new system that allows us to experience some revolutions, or coup d'états and wars of succession in the future.
