I feel Dan is probably still patting his own back for the accomplishment.
They were looking for the best way to move him from a dead timeline to the main continuity and the best way Jurgens came up with was to have Jon's family hiding with him for the whole time in the new world.
But, yeah, as he told, when Dan started pushing to Didio that the kid could be the future of the franchise and he should end up somehow in the main continuity, he suggested he could be put on a rocket or something. It was a random idea though. DiDio wanted the baby to be aged up, and Jurgens suggested the idea of the whole family hiding and Jon "aging up" there. The rest is history.
