Remove pathology until it's balanced.

Yeah, metaneural haze, pseudonecrosis and skeleton stuff should really be marked as harmful. There is precedent for this too with ethanol production.
As for SMES, it is beneficial the vast majority of times, so that is just sort of "sucks to be you, cyberperson", imo.

The problem is less cyberhearts and more that it prevents defibs from working, and they're the only way to fix a stopped heart so.
