What does heavy cruiser mean in a 1919 design exercise?

The argument turns on whether a later treaty category should define a ship intended for 1919. Alex Clarke describes Hawkins as a development of the light cruiser and the proposed station flagship as a modern armoured cruiser. In that earlier setting, the 9.2-inch gun belongs to an established British cruiser tradition. Foxo instead tests the designs against the eventual treaty definition and favors his 7.5-inch ship. The counterargument is that building a large new class before the treaty could change the definition itself. The dispute shows how a historical label and a counterfactual procurement program can imply different design limits.
