My "history of the Omniverse" head-canon:
- OG Earth-2 is the original version of the Metaverse, from before the Omniverse's first expansion.
- The creation of Earth-1 as the new Metaverse marked the beginning of the First Multiverse, which encapsulated Earth-2, Earth-3, Earth-S and all of the original Earths that were seemingly extinct during the first Crisis.
- After COIE, the new Metaverse known as New Earth's universe would have no knowledge of the survival of the previous Earths, as it would stand as the sole universe of its new multiverse. It's first contact with the larger Omniverse would have been Infinite Crisis.
- Then Flashpoint happened and the Metaverse became the New 52. Like OG Earth-1 before it, New Earth's multiverse was also preserved and Morrison's Multiverse gravivated towards the new Metaverse, resulting in the multiverse we saw in Multiversity.
- After Rebirth and Death Metal, the Metaverse kept evolving and now there's a new multiverse around it.
So the current Omniverse would consist of:
- The Original Multiverse: OG Earth-1, Earth-2, Earth-3, Earth-S, Earth-X and so on.
- The Unified Multiverse: New Earth as the sole universe.
- The New 52 Multiverse: New 52 Earth-0, OGN's Earth-One, New 52 Earth-2 etc.
- The Infinite Multiverse: Post-Death Metal DCU and all the new Earths connected to it, like the new Earth-3, a Future State Earth, Earth-M etc.
- Other Multiverses without close ties to the Metaverse, like versions from other media.
In this scenario, everything would be preserved and the main DCU (current Metaverse) wouldn't need to be te answer to every single desire of the fans.
