Not in the case I'm talking about. In that case, "if there's no debate possible, we return the file extension. Otherwise, we return the empty string", all I'm saying is that I believe it should be: "if there's no debate possible, we return `Optional.of(the file extension)`. Otherwise, we return `Optional.empty()`". So for `"text"` there's no debate possible and you get `Optional.of("")`. For `"text."` there is debate possible and you get `Optional.empty()`.
