In the offline, @guihecheng also has the similar or same question. I think I did not use it because it has more than what we need (ex: bytes used, keycount, seqID, placeOfBirth, state etc...). Are you ok including with them? Not sure we really use all of them. I am also ok to create small proto structure including only DNDetails and Index.
