And even if it I destroyed, there are parallel universes with dead Supermen on them because Darkseid visited multiple universes and killed Supermen in each one, there's vacancies to fill, and they can write in Starman to send Supes and the family there.
The only real problem I have with Pre-Flashpoint Superman is largely the problem of writers in making him not present at big crises. Doomsday and being engaged to Lois didn't stop him from being a hero willing to risk his life then, and yet suddenly DC writes him off as no longer putting the world first. Writers at DC neuter Superman badly, or at least didn't plan the whole backstory for Pre-52 being on Prime Earth very well, if at all. I don't hate an older version, but writers and editorial at DC are horribly incompetent and stripping away base attributes of courage and heroics that Superman used to have. Family shouldn't stop Superman from putting his life on the line for the greater good of humanity, it did not do so before in prior continuity. Even Lois understood that.
