// I don't remember why I decided to write down the date I found out about it. Maybe I considered that monumental of a discovery.
// 
// However, we still use ReadUnregisteredKeyfields() since GetKeyValue() only supports a string while this function was used for entire variant_ts.
// It now calls GetKeyValue() and returns it as an allocated string.
