My guess (and it is only that) is that the Pi5 PMIC implements overvoltage monitoring and a high-side switch to isolate vulnerable parts of the Pi.
A shunt (as used on previous models) gets serious at a 5A rated current -- leading to more possibilities of failure of the protection in a non-safe manner.
I have never been entirely happy with the Pi4B style of shunt protection that relies on external current limiting.
