Colin Chapman, Brit developer of Lotus sports cars, was asked how he planned to make his cars faster. His response was, "Add lightness." (instead of adding larger, heavier, higher horsepower engines).
In the same manner that is exactly what backpackers on this site try to do - add lightness. We do it with multi-purpose gear, advanced materials like Cuben fabrics, carbon fiber, etc, and reducing true non-essentials.
And of course you SUL backpackers are the greatest proponents of adding lightness. You guys (I'm still UL) know this is the way to go for more enjoyment. Then there's the added benefits of fewer joint and muscle problems, greater mileage when desired, and fewer items to keep track of in camp.
So keep on with your quest to "Add lightness".
