Heat + electronics = FAIL

On top of that, why even bother with PWM control?
Current mechanical WG + EBC = PWM control.
I'd rather go stepper motor control if you can get the electronics to hold up to the heat...

True WRT heat + electronics = failure, but there's no reason that you would have to mount any of the electronics near the turbo, and if concerned about the solenoid or stepper motor WG actuator, those too can be mounted remotely in a more benign location via some type of cable or rod linkage.

As the OP suggested, a completely electronic WG control & actuation function would allow you to bypass the turbo on demand, like running in "N/A only" mode for economy. In a mechanical WG + EBC = PWM control setup, you still can can't limit boost below the WG spring tension. Of course your right foot can keep you out of boost just as effectively, but that's no fun.
