Overall, I like the idea a lot and I think it's weird its not in the game.
My sole concern is how much it will screw with the Sansha method of enslavement because of how total it is.
What do you mean by that?
The fundamental of the True Slave technology is the complete and total enslavement of the person, body and mind. It has since evolved to become much more, but that basis is still there. It achieves this function in its invasive properties to the brain, as well as the presumed mental indoctrination/adjustment being apart of the Sansha network entails.
To be able to simply "right click -> liberate" a Sansha slave throws the entire process out the window. Sansha slaves are notorious for being unsaveable, or requiring such a vast amount of resources to 'bring them back' that it's just not economical on a planetary scale. You have to contend with not only the extreme physical modifications of the individual, but the mental adjustment they underwent being apart of something so 'transhuman' in nature.
I actually doubt if its possible for a deimplanted Sansha to ever adjust to a normal life. I will have to check the Burning Life, but I'm fairly certain the Sansha operative in there remarks on this exact subject. Will edit with it in a bit.
Edit; here it is. "No, it's...it's not even hard to get the
old ones back. I don't know if it's proof of humanity's darker nature or what, but we agents always come back to Nation eventually."
