Attribute '#[serde(default = "...")]' is not reflected in the schema

[ensh63]

utopia::ToSchema macro documentation says that serde default field attribute should be used in the schema (see here). But this simple example does not work with utoipa v.4:

fn default_prop() -> u64 {
    10
}

#[derive(Deserialize, Serialize, ToSchema)]
struct S {
    #[serde(default = "default_prop")]
    prop: u64,
}

Generated code:

impl<'__s> utoipa::ToSchema<'__s> for S {
    fn schema() -> (
        &'__s str,
        utoipa::openapi::RefOr<utoipa::openapi::schema::Schema>,
    ) {
        (
            "S",
            utoipa::openapi::ObjectBuilder::new()
                .property(
                    "prop",
                    utoipa::openapi::ObjectBuilder::new()
                        .schema_type(utoipa::openapi::SchemaType::Integer)
                        .format(Some(utoipa::openapi::SchemaFormat::KnownFormat(
                            utoipa::openapi::KnownFormat::Int64,
                        )))
                        .minimum(Some(0f64)),
                )
                .into(),
        )
    }
}

Addition of #[schema(default = default_prop)] corrects the situation, but this attribute duplication looks strange. Is it possible to avoid this duplication?
