Isso não adiciona nenhuma segurança extra à sua API; as *operações de rotas* ainda estarão disponíveis onde estão.

Se houver uma falha de segurança no seu código, ela ainda existirá.

Estes exemplos são intencionalmente simples, porém mostram como tudo funciona.

Nos capítulos sobre segurança, existem funções utilitárias que são implementadas desta maneira.

Se você entendeu tudo isso, você já sabe como essas funções utilitárias para segurança funcionam por debaixo dos panos.
