Turbosupercharged aviation engines are/were designed to make full power at some critical altitude. Below that altitude, the waste gate is opened incrementally to some pressure value so that the intake system or pistons don't rupture. Above that altitude, the waste gate is fully closed and and power begins dropping with increasing altitude.

So, the waste-gated overdriven compressor is nothing new.
