Not sure what your point is but if it's to suggest that the parking
brake could be used to stop a car while it's under near max power,
that won't work. *They are intended for parking only, the brake pads
are smaller than the main pads,
Not true. The parking brake uses exactly the same pads that the service brake
uses, except (as noted) on only two wheels instead of all four.
When using the rear brakes with the brake pedal, they give about 20% of
the braking power. *That is with vacuum assist! *Using the parking brake
lever or pedal they provide even less braking power with no vacuum assist.

On many cars with read disk brakes the "parking" brake is a VERY small
drum brake inside the rear rotor and will have virtually NO effect on
slowing the car at speed, in gear or out.

That's news to me but either way we both know the parking brake isn't
going to stop a car at highway speeds and full throttle. *No argument
from me.- Hide quoted text -

Yep, If the service brakes won't do it, the parking brake for sure
won't.

Now, if the parking brake is on a separate drum or disk, or something
that hasn't already been heated up by the service ones, the parking
_might_ finish stopping the car if it was already down to slow speed
by the service brakes. That's about it.
