Deletion of Heraclius (son of Constantine IV)

Comment: We have tens of thousands of BLPs (and BPs) on WP now that fully meet , but whose article will be deleted in the coming decades.  Even now, we see them at AfD.  Their RS wanes, and editors realise that while GNG is a guide, it is not the only criteria.  In 1,000 years from now, Heraclius still will be recorded by historians.  Unlike the reference to Eric Trump above (who does not become U.S. President if his father dies), at a point in time, Heraclius was the 3rd most important person in the western world, and would have had plenty of contemporary RS/GNG notability (long since gone, probably deliberately so given his brother). The most important man in the western world at that time (Constantine IV), sent a lock of his Heraclius' hair, and the hair of the 2nd most important person (Justinian II), to the most important western religious leader, Pope Benedict II; and it gets recorded in one of the most important books of that era, the Liber Pontificalis.  This is not a nobody

Comment: It seems to me there are (now) sufficient reliable sources. I am going by  and its first bullet point qualification. All that apart, it would be silly to delete this and  advises towards using common sense

Comment: to his father. He is a mere footnote to history.  If we had substantial sources as to his life, showing what he did (apart from merely existing), he might deserve and article, but often even for royal family members in ancient history, we know nothing and probably never will.  Having such articles is not helpful.  They have to be tagged as stubs, but that is to invite , i.e. invention or fiction

Comment: There's sufficient sourcing here for a stub article IMHO, but merging the little amount of content here to his father's article would be absolutely preferable to outright deletion per
