Also a note that using a Field would require a serialization/deserialization every time the extension type is used (whereas some core "datatype" based on the `ExtensionType` is parsed once on the way in and serialized once on the way out. > What should be the behavior of a = b according to DF core's logic? Even if it doesn't know about extension types, it could always calculate equality for dispatch on `extension.name` and equality otherwise based on `extension.name` and `extension.metadata` being byte-for-byte equal. (An ExtensionType implementation, perhaps registered with the session, could provide smarter logic). -- This is an automated message from the Apache Git Service.
