Yeah, I'm actually surprised the hardware hasn't caught on accordingly:
while it's now standard for chips to monitor their temperature (and
adjust their power consumption if it gets too high), I still haven't
seen anything comparable that would detect and report when the input
voltage goes out-of-range (and maybe also take steps to reduce the
instantaneous power consumption?).
Instead, we're in the dark, forced to try to avoid the problem
by over-provisioning the power supply and pray that it was enough.
