A duplicação de código aumenta as chances de bugs, problemas de segurança, problemas de desincronização de código (quando você atualiza em um lugar, mas não em outros), etc.

E esses modelos estão compartilhando muitos dos dados e duplicando nomes e tipos de atributos.

Nós poderíamos fazer melhor.
