I would personally argue that the Star Wars universe would not be connected to the force, as allowing them to be would essentially cause a Keymind to be an unstoppable powerhouse plus nearly infinite Force powers. Additionally, it would be wrong to make changes to one universe to match the other. However, not being connected to the force means that most force powers are useless against them, as is evident from the Yuuzhan Vong. The Halo rings would wipe out all life because of sentience, so crippling the force is useless.
