It would likely be a even more complex setup, as the vacuum pump needs to be controlled depending of the engine load/rpm, needs to be powered, etc.
This being said It’d be interesting if anyone has had experience with an actuve setup to share... I recall reading that some high end sports car do have such setups - BMWs possibly.
