Now that the infinite multiverse has been restored:
The comic books that DC has published under its imprints that otherwise had zero ties to the DCU, like V for Vendetta, Preacher, American Vampire, Sweet Tooth, and any of the Hill House Comics will now be alternate dimensions. Hey, if Watchmen turned out to be an alternate universe that crossed over, why can't they? And crossover books like JLA/Avengers, Batman/Teenage Mutant Ninja Turtles, and RWBY/Justice League will also be the DC multiverse's ties to the other multiverses of the Omniverse now that the Source Wall is gone.- In addition, modern Elseworlds and out-of-canon stories like Batman: Wayne Family Adventures, I Am Not Starfire, Batman: Nightwalker, Superman Smashes the Klan, and DCeased will retroactively have been revealed to be Earths in this new infinite multiverse.
