At the end of "Secret Wars" #9, Hickman clearly implies that things happened much differently after Reed et al put space and time back together.
Some series, such as "Stand Off" or "Secret Empire" have made passing reference to the incursions. Other series, such as "Jessica Jones" or "Iron Man" have implied that few people remember, or should even know. Make of the contradiction what you will. (For the purposes of this conversation, ignore stuff like "Ms. Marvel", "Squadron Supreme" or "Web Warrior". Those series are too derpy, or just editorial cluster-f_cks, and are best ignored.)
The easiest thing to do is to accept what Hickman wrote, and assume that the incursions did not happen (at least not as presented in Hickman's run on "the Avenbers" and "New Avengers"). If the contradictions are still too much, assume mischief from the Molecule Man or the fluid history implied by Ewing in "the Ultimates". I doubt that Marvel is going to address this in any significant way, so simple is probably best.
