 **2. Only use native serialization methods**
 This option was originally considered, which would have effectively removed the use of the `TypeConverter`s in favor of a simple `JsonConverter`, but it was pointed out that this may result in lossy conversion between primitive types. For example, when converting from a `float` to an `int`, the primitive may be truncated in a way by the native serialization methods that does not provide an accurate result.
