I think it's more a leftover of Taylorism, where you cut tasks into bits small enough to not need craft and have an army of untrained and exchangeable workers do it. Workers don't have enough agency to significantly pervert the metrics. They can cut corners and/or work slower, but that's not inherently related to the metrics, and there is no long term view for the workers in the first place.
