IIRC it is done so that you can choose to match the locks upon purchase, buy replacements, stores are motivated to carry lock cylinders, and you can expand based on what you already own. (Don’t shoot the messenger :)
It probably also has to do with how contract manufacturing works.
This is the reason. If you have multiple or existing ones you have the ability to match the lock number to use the same key for existing and new locks. If you buy different items that require locks you buy locks with the same number straight away.
