The way I see it is this :Maybe but to export it you would have to do exactly that. The fact that you could have a 'special location' downstream in some cases may not be relevant. I could have a bathroom in this downstream location but could still employ the TN-C-S derived earth.
if you have a tnc-s /pme earthing system, and it is taken to an outbuilding that is out of the equipotential zone of the property then you would be exporting it.
If the building is within that zone and no extraneous, then you would be utilising the cpc.
