Right because manufacturers would never need to know when a particular tank was "born".
Or what batch it came from.
Or need to cover a warranty from the date of manufacture of the product.
Or they always love to retool their stamping for those bottles that "need" vs those that just have it on their "because".

TL;DR hole size controls how fast balls get spent
