it is like that by more traditional materials and "less squeezed" packages for easier spooling, lower end materials, less cost, comparing to F1..
main purpose was to decrease heat goes to into engine by Merc's split turbo design.. since there is a place more likely split turbo gave a better placing opportunity for the generator it increases efficiency as well..
compressor has to be in the back since exhaust piping goes towards back in a small area of engine compartment.. putting intake turbine in front gets rid of the engine heat and less heat means more power obviously.. and since there is less heat smaller intercoolers for better aero efficiency and better center of gravity as a bonus by split turbo and intercoolers..
the only thing im wondering is how they manage to keep the vibration stresses away from split part.. there is a longer shaft between turbo elements, its in the middle of the engine + track bumps, acceleration etc.. tiny tiny off center move can ruin the shaft easily..
im not sure if there wouldnt be electric generator Merc' would go this way.. but more surprisingly none of the engine manufacturers thought about this but Merc'.. great engineering move to step up..
