Well it is certainly an option either way. New timeline Nero already caught wind of it and joined back up with the Ironworks to pester Cid about it (along with helping find the cure to tempering). And while not confirmed just yet, opens the door to a lot of my personal head cannon theories.
Just an example ruined by the pandemic: The meaning behind a certain lyric in Locus- a theme reused for The Twinning.

Now it was mentioned by Koji Fox that it was just a random line that he felt clicked and was catchy. In my dumb brain, I read it as a date. 7/23/23. A possible pre-pandemic 7.0 launch day. With Alexander being time travel central, I wondered if it was a major clue as to the nature of the hypothesized expansions story.
Doubtful if anything else is behind it. Just one of a bunch of long shot "what ifs" that I have. Again, ruined by the pandemic. Or is it....
