This is not a fantasy world, in truth touch voltages are utterly insignificant, there are no magic RCD's that can somehow reduce the magnitude of an electric shock without even disconnecting the supply!
This is the real world where we only have simple physics and that is all, continuity, resistance, logic and common sense.
Therefore we are now, always have been and always will be 100% reliant on EEBADS and loop impedance; and now we simply need to reduce our disconnection times from 0.4seconds to 0.04seconds if we are to achieve the stated claims of the IEC.
Having now spoken to you for quite a while, it has become obvious that the prohibitive price of RCD's was not the only issue back in 1991:
If at least some of us had not mastered the art of insulation resistance testing before their introduction, people like you would have thrown the lot of them out of the window claiming that they were unusable due to nuisance tripping and we never would have been able to progress at all!
P.S. Being considered 'extraneous' obviously makes a radiator an extraneous-conductive-part and therefore, back in our real world, they must be connected to the main earthing point of the installation, therefore providing us a measured/calculated loop impedance and therefore a predictable disconnection time if that radiator should come into contact with a hazardous live conductor! (simple isn't it)?
