In the UK you have to tell the DVLA when you sell or buy a car so they can keep ownership records - this is useful because when you get caught speeding by a camera (for example) the owner is legally responsible and can be found. This doesn’t need annual updates, though we pay car tax annually so we’re unlikely to forget to update the DVLA if for example you move house.
I always thought this could be talking about the weapons, e.g. imperials had fancy well made guns that made a precise impact, whereas sand people used cheap homemade shootaz which made messy holes. No idea if that’s true in lore though.
