How early turbine cruisers accelerate the machinery chain

What changes if the Topaze-class protected cruisers are built with steam turbines from the start?

Later British cruisers would adopt turbines earlier, pulling boiler-pressure and machinery development forward by about a decade.

A successful turbine installation in the Topaze class would create a precedent for the cruisers that followed. Production experience would spread through the fleet rather than remaining confined to a few experimental ships. Turbines also raise the importance of boiler pressure, reliability, and the industrial chain supplying the machinery. These changes could pull cruiser propulsion and boiler development forward by roughly a decade or more.
