How to declare Nullable property

[FaustVX]

I just wondering.
What is the preferred way to declare a half-nullable property ?

private object _obj;
[DisallowNull]
public object? OBJ
{
    get => _showOBJ ? _obj : null; // May return null
    set => _obj = value; // Must not be null
}

private object _obj;
[MaybeNull]
public object OBJ
{
    get => _showOBJ ? _obj : null; // May return null
    set => _obj = value; // Must not be null
}

The guideline used in runtime repo: https://github.com/dotnet/runtime/blob/main/docs/coding-guidelines/api-guidelines/nullability.md#nullable-attributes

TL; DR: DisallowNull is preferred over MaybeNull.
