I was quite surprised to read in this question one very interesting detail about the system used for Saturn V launch release. Saturn V employed a system of pins and dies such that when the hold-down arms released, the first few inches of initial motion drew tapered pins through extrusion dies. This had the effect of damping the shock of launch release (from 0 to about 1/6 g).
Has either this specific technique or some other means to achieve the same purpose been used on or proposed for any other launch system? If not, was this done out of an abundance of caution in the face of unknowns, or was it found/known that without this measure, things would indeed break?
