And with J'onn giving everyone their pre-Crisis memories, we can hardly trust anyone's word when they are speaking from Earth-1 memories. If Diggle's wife introduces herself as Lyla Michaels, wouldn't that be the Earth-1 Lyla speaking? If Clark didn't know he had two sons, would Lyla know if her name was changed? Okay, she'd probably have an ARGUS ID she could have read. But if John Diggle ever recounts his time in the army, is it trustworthy if it's his Earth-1 memories? How much of his time would be just from Earth-1 and what really happened in Afganistan in Earth-Prime? We won't know. The only valid backstory we would ever have for Earth-Prime characters would be the differences from Earth-1, Earth-38 and Earth-BL, and information from characters J'onn hasn't touched. But if J'onn restored more people's memories and some people start remembering Earth-1 on their own, we would be in a real tough spot about Earth-Prime backstories.
