I do not think we can compare the bellcaps under discussion to the decorative cups found on the pugio rivets, for these are simply cups with a hole in there center and are there on the pugio as a cosmetic device.
The bellcap has it's hole punched from the outside top of the dome which creates a countersink that has a definate engineering function to it, they were made this way to greatly reduce the amount of riveting poundage when a rivet is peened down.
