Why do US 120 VAC power plugs have holes in the end of the blades?

To allow you to put the shackle of a small lock through the blade to
ensure the item can't be plugged in for use?
I suspect it's to mate with a small boss on the blades of the socket, to
make it less likely to jiggle loose. The British solved that problem by
the traditional method of "add mass until nothing breaks."
I always marvelled at how the Yanks got away with such flimsy plugs when
half the voltage means twice the current for the same load power.
