The Netherlands do not allow dual citizenship, so simply allowing all the Belgians/Dutch to chose during an Enclave/Exclave swap wouldn't be possible.
It wouldn't be necessary really, as citizenship is more dependent on your parents. Both of them being EU member states also makes residence somewhat irrelevant too, except maybe with taxes.
