O parâmetro `name` **ainda é obrigatório** (não *opicional*) porque ele não possui um valor padrão. Mesmo assim, `name` aceita `None` como valor:

```Python
say_hi(name=None)  # This works, None is valid 🎉
```

A boa notícia é, quando você estiver no Python 3.10 você não precisará se preocupar mais com isso, pois você poderá simplesmente utilizar o `|` para definir uniões de tipos:

```Python hl_lines="1  4"
