Creational patterns' independent evolution from inheritance to composition (Factory Method subclassing → Abstract Factory delegation → Prototype cloning) parallels OCP's historical evolution from Meyer's inheritance-based version to the polymorphic abstraction-based version, constituting convergent evidence across orthogonal GoF categories — both the "what to create" and "how to extend" concerns independently migrated toward composition.
Two independent evolutionary trajectories converging on composition is stronger than either alone
