Yeah. That’s really not that long in comic terms. For something as huge and redefining as that idea, five years isn’t even enough to let it ripple out into the rest of the universe. And that’s when there’s parity between the time passage in the books vs the real world. A month between issues may only be days or a week in-universe. I’ve never kept track of how long things were in continuity though, so it may have parity, I’m not saying one way or the other, just pointing it out as a factor.

From what little I’ve seen of the newer stuff, it’s basically an excuse to wipe out what happened and go back to regular comic stuff. Which is pretty disappointing. The idea of it was brilliant, and in universe, nothing would ever be the same again. Trying to do away with it without a total reboot is a bad joke on anyone that partook of the stories involved. And a reboot is just a trope at this point.

They could have just set it up as a “what if?” only long term. That would at least make it less of a waste. It would still exist as a separate continuity and make sense.

For a people who solved mortality, definitely so.
