I kind of look at it as a view of the Kaminoans perception and morality regarding their industry, and various issues.
for some reason the Kaminoans do not have a very high opinion of clones. and In a way I totally get it, to them they are a product, mass produced and interchangeable.
2 they have a contract, and the impression I always got was that to the Kaminoans a contract is pretty much sacred.
the vast majority of the clones were produced to more or less identical specifications (genetic clones of Jango, with tweaking to make them have less individuality, and less questioning of orders)
with that said there is either some issues with the cloning process they use, leading to a certain percentage of "losses" (read mutations) or they are occasionally introducing batches of clones that have slightly different specs, (read genetic engineering to see if they can get some "better" results that lead to a higher quality product)
