It's true there is currently no perfect analogue for the "cursed" item, though the faulty prototype system comes quite close in its effect and how the player treats them.
The biggest problem with a curse-like effect is that it doesn't fit well into the lore. Once you find out what Cogmind is, an inability to simply detach a part at will might seem absurd. (Certainly you can find other absurd things, but this in particular might feel more so, and therefore a highly "gamey" concept, which I'm trying to avoid in general.)
