That's not novel. In quantum cosmology there are theories where primordial black holes appeared as fluctuations of some quantum field. In cyclical universe models primordial black holes are leftovers from previous cycle.

Are primordial black holes supermassive?

Don't know anything about the topic but saw you downvoted for asking a question so went down the rabbit hole. Turns out that no, primordial black holes aren't supermassive. In fact one could call them superlight since they could be the size of an atom.

Yeah I think I was downvoted because that’s fairly well known in cosmology and is a refutation of the parent comment.
