Simply shutting down fuel and/or spark works best as a rev limiter,
not a mixed operation mode. Or at least the way it was implemented
on the cars I've ran into the rev limiter. You may get less handling
upset that way, but it isn't a particularly unnoticeable or pleasant
way of cutting power.
Suspect you'd need to pop valves to cut pumping losses to make it
at all worth while.

Yes, that's why a reman generator is probably $300! But if it's a
restored show car you have to have the generator.
Alternators are better in every way but one: they need external
excitation power.
They COULD build a PM exciter in the alternator, but that would cost
money. It's irrelevant on modern cars because you need to run the ECM
to run the engine.

Suspecting that much just by the replies here and some other research.
Although I might just build the circuit to find out if it does any good.
