Nearly all crisis events DC has done have altered the history of the DCU to varying degrees however the crisis events Scott Snyder has done have been different, instead of just rebooting the dcu they have expanded it's lore and more specifically it's cosmology, dark nights metal introduced the dark multiverse and dark nights death metal FINALLY gave dc an omniverse, this what dc should do with it's crisis events from now on, no more reboots instead create new places and ideas for the heroes to explore.
