The ironworks feat simply caused the timelines to diverge, that timeline may endure, but it was not changed. So even should the Ancients have resorted to time travel, it would create a new timeline but not alter their own. I'm not saying btw the sundered arent necessarily non-inventive, but they are weaker than the ancients in some respects.
Omega is not an unsundered, but rather a being like Midgardsomr. A being outside that paradigm. Furthermore, it took the usage of the Crystal Tower. A structure build by "lesser" beings.
