What other domestic items need a 6mA DC leakage detection?
The 6mA DC leakage is, as I understand it, due to the CP/PP lines, not the HV battery. There are multiple independent insulation systems in an EV, as well as a pair of contactors that get thrown if isolation goes bad. It is hard to imagine that the DC from the battery could in any way get exposed on the AC charging pins or PE.

In practice the non-isolated DC section of a typical SMPSU is small and localised and unlikely to cause significant leakage. The DC bus of an EV is much more extensive and more at risk of generating sufficient leakage to blind a type AC RCD. You mention SMPSUs with active PFC; they are not a special case for DC leakage.
