The descendents of the emperor who manifest their powers as immortality, chaos free warp powers, and being very good people, are they still cannon?

They feel very old lore, with their ties to the star child and them being a genuinely good group of people because of their connection to the big E. Not to mention if they were new lore their immortality would probably be them being perpetuals, not just ageless humans.

But I tried looking it up and didn't see anything contradicting them existing. Are they just forgotten old lore not officially retconned but not really a thing anymore?
