What has become of the Dark Multiverse?

Not the universes themselves - they were born dying, so they were never eternal but were forming and dissolving; based almost on a cosmic Murphy’s Law. I’m talking about the DM itself.

Did The Hands’ reboot totally eliminate the DM? And is the Dark Multiverse the Prime Earth equivalent of New Earth Hypertime?

Has there been an Earth -3 - a Dark Multiverse version of the Crime Syndicate’s Earth? Maybe in The Terrific’s?

I’ve seen discussions (obviously wrong, but interesting) on Reddit where Earth 3 itself is compared to a Dark Multiverse; as the Crime Syndicate is a nightmare vision of the Justice League; and in the New-52 (and JLA:Earth 2) they did escape their world (à la Dark Knights) as it was being destroyed.
