Increasing the effectiveness of engine-braking would be another advantage in a, let's say, "hybridized" turbocharger coupled to a starter-generator to overcome turbo-lag and recover energy. Coupling would be similar to what is used in the generator of modern jet-powered airliners.

Sometimes, even the regular fixed-geometry turbochargers get under scrutiny for durability and ease of maintenance issues.

I'd have thought a simple supercharger for twin-charging would be better... but having a standalone electric supercharger would make for much simpler plumbing and installation than twin-charging.
I don't understand how an all-electric supercharger would be easier to do the plumbing, even though it wouldn't require a mechanical drive.
