Not OP, but my take is that stability is usually defined as a base-state that will continue onto perpetuity unless some outside force disrupts it. Resiliency is more closely defined as the ability to recover from disruptions back to the base-state quickly.
Since the context here is that efficiency can remove layers of redundancy therefore allowing disruptions to wreck more havoc - I believe that's what OP was getting at.
