Having intimate knowledge of the systems at play, I would disagree with the idea of enforcing this sort of thing. Not just for the player loosing a limb, but also the players that may inadvertently remove a limb without meaning too.
This aside, the process involved of getting one and the prerequisites for some can be unfair, especially those early to the game.
More over, the cyberdocs work for that sort of thing is incredibly unrewarding for the most part.
I like having more cyberware out there especially for cyberpunk style body modifications. But Sindome for the most part appears to be rather opposed to the idea of cosmetic cybernetics from the ground up if you look at the systems and economy from the ground up. WHICH IS FINE, I hasten to add, chasing after that sort of thing is a big choice and socially frowned upon like some might 20 years with people who have extreme body modifications
