[Marvel] With the collapse of the multiverse following Secret Wars #1 (2015), how have dimension-based powers survived (e.g., Nightcrawler, Cloak, Spot, Cyclops, etc.)?

For clarification, I specifically mean DURING Secret Wars and after. I know after Secret Wars ends with them slowly recreating the multiverse, but I doubt they started with all their friend's/enemy's dimensions so they could have their powers.

Extra credit: Did they talk about how or why Spider-Gwen's universe was unaffected by Secret Wars events?

I think there is a difference in the Marvel Omniverse between a "Dimension" and a "Universe". Like each Universe has its own version of the Nine Realms, but all those realms are different Dimensions.
