In a parallel hybrid you need everything, what pure CE car has, like gearbox, clutch, differentials, propshaft, rear-axle release clutch, race-tune engine and on top of that you add electric motor and battery. When you use EV with CE generator and at least two motors you can skip most of that CE stuff, at least the gearbox, both clutches, propshaft and transmission hydraulics. On top of that you get active torque distribution between the axes which current WRC cars don't even have.

Just look what the parallel hybrid system brings to the current cars. It is very expensive but when it doesn't work the change in stage times is minimal and there is basically no fuel saving either, so what is it good for except for the word HYBRID on the banners?
Because a parallel hybrid works well in other racing applications.

The current spec system is hardly representative of what could be done with a parallel hybrid. It's as you said just a ad on like the WAE system in LMDh cars, but those cars are far from the be all and end all of what can be achieved.
