The problem is that that leads to epistemological issues that fly in the face of real-world reasoning. Instead of worshiping at the altar of A/B tests, one can focus on the things that matter operationally. Stateless cattle are a tool, one of many, but they are not the end-all and be-all of operation any more than constant Gentoo-like recompilation for performance improvements "just in case" are.
Process matters, and the Operations side of DevOps have formed a new, artificially restrictive religion around this design methodology.
