OCP's historical evolution from Meyer's inheritance-based version (1988) to the polymorphic abstraction-based version (associated with Martin in the 1990s) parallels the GoF's composition-over-inheritance principle, suggesting that abstraction-based extension has largely supplanted implementation inheritance as a primary extension mechanism.
OCP's own history recapitulates the broader paradigm shift — convergent validation from principle and practice
