Before, if a product fails, it will be made stronger by adding more material or redesign it bigger for better.  Whether the rest of the design was just good enough or make it x times stronger than the first one. Over time, products that never failed were targets for cost reduction as business decision.  It was not a technical decisions anymore, but business cost reduction as it is likely. The design nowadays  would offer the “weaker”  product, the more it was “closely” engineered to lower the cost. It is designed closer to the expected loads. Hence, the need to read the fine print of the manual before using any product.
