I'm the "why" camp. Headsets generally don't require frequent servicing anyway, so I don't see the point or the logic of pounding out the cups. Unless the races are pitted or there is evidence of corrosion, the races can easily be inspected and the bearings re-greased without pounding out and repressing the cups.
