D.C. Comics is just realizing something that mylar-bag hoarding fanboys have known for time immemorial: continuity is a bitch, a crutch in telling stories about superheroes who can't profitably age along with anyone reading along at home. Bruce Wayne can't really ascend to his fifties; Peter Parker doesn't make sense beyond maybe the age of 35. Traditionally, the crutch of continuity has meant that every couple of years the D.C. powers-that-be cook up some sort of crossover event that allows for the jury-rigging of continuity: your Zero Hours, your Crises On Infinite Earths. All of this tinkering and nipping and tucking was obvious, disheartening, and lame; I haven't collected DC comics in years, but when I recall how the gritty, universe-in-disarray Legion of Super Heroes was skunked in the late 1990s, I still get irate.
