True, eventually the Molecule Men time bombs set by the Beyonders would have done so as well, without an opportunity to save anything (we think, since after all who knows if the same technique Doom used to preserve fragments of worlds couldn't have been used without Incursions happening), but not for about another 11-12 years, based on Molecule Man appearing in the early days of Marvel and the sliding timeline only going 13-14 years so far. Plenty of time to figure out a different solution to that problem, had the multiversal collapse of the Incursions not been breathing down everyone's neck.
