> Currently, if a function requires an argument of array with specified element type, we are limited to ExplicitArgumentTypeStrategy. This unintentionally modifies the original nullability, which interferes with the output type inference.
> We want to add new argument strategies like RootArgumentStrategy and FamilyArgumentStrategy for array to preserve nullability whenever possible.
