I am going by how my Tiguan works on “Auto Hold”. When its on it is both holding the vehicle on a hill and to top vehicle creeping as its an auto and also when you come to stop and park up it turns the parking/handbrake on.
I think on many recent cars cars “Auto Hold” does the job of everything in applying the a parking/handbrake.
