Mas você não está restrito a usar um modelo de dados, classe ou tipo específico.

Você quer ter apenas um `id` e `email`, sem incluir nenhum `username` no modelo? Claro. Você pode usar essas mesmas ferramentas.

Você quer ter apenas uma `str`? Ou apenas um `dict`? Ou uma instância de modelo de classe de banco de dados diretamente? Tudo funciona da mesma forma.
