We can't tell if any consumers are ever going to appear, and the regulator having a voltage outside of the constraints is an urgent problem we need to fix quickly. Since we try to bring the voltage to the nearest end of the constraint the driver could always change the bogus voltage it reports to one that is excessively high, this would mean the core will try to bring the voltage down to the maximum rather than up to the minimum. The driver could also look at the constraints when guessing at the hardware configuration rather than claiming an out of spec voltage, this would mean we wouldn't need to correct anything.
