It sounds like badly documented code then. A function, especially if some kind of API boundary, should absolutely state whether it can or can’t return null.

Ideally everything should be non-nullable, with optionally specified nullability.

Of course, in the type system.

Just like we're "documenting" types themselves in the type system and not in JavaDocs.
