JSON property is missing from schema when using conditional serialization

[omfgicbf]

With a model that has a property that is hidden using ShouldSerialize, e.g:-

public class TestModel
{
    public bool Foo { get; set; }
    
    public bool Bar { get; set; }
    
    public bool ShouldSerializeFoo() => false;
}

The schema generated for this model excludes the Foo property when the model is used as a response (as expected) but it is also excluded when the module is used for a request.

As this Foo property is only excluded from serialization, and not from deserialization, I would expect it to be present in the schema.

In addition, if the conditional serialization of a property relies on a value that is set only under certain conditions at runtime (and which is not satisifed when NSwag is run), the property is exlcuded from the spec.
