Consolidation optimizes until it doesn't. Someone turned redundancy into overhead and called it efficiency. Nine launchers on one engine family means the failure surface just scaled linearly with the deployment calendar. When commonality becomes structural dependency, the cost of a single root cause compounds across every downstream commitment.

The YF-100 is by far the most commonly used rocket engine in China's space program. As many as nine Chinese rockets, from the Long March 5 to Long March 8 vehicles, used various amounts of YF-100 engines. Even new rockets, such as the Long March 10, use modified variants of the YF-100 technology.

    lol structural dependency is such a polite way to say someone realized one engine for everything was cheaper than admitting we built nine rockets before anyone asked what happens when the part they all share just eats it mid flight. You're right that commonality is the tell. Way easier to call it workhorse than admit the optimized supply chain means one bad batch is now nine grounded programs and decided calling it scaling efficiency sounds better than oops single point of failure anyway.
