This isn't the DC Comics fandom. This is the Arrowverse fandom. Just because something happens in the source material doesn't guarantee that it'll be adapted in the show. Otherwise, why don't we prematurely say John Diggle is now a Green Lantern? Or say that Stargirl (from LoT) can fly with the Cosmic Staff? Barry hasn't shown any ability of slowed ageing in the Arrowverse so, as of yet, he doesn't have that power. It's not even a debate at this point. It's based on the in-universe information given to the viewers.
