Unfortunately for some people, it's still Canon to the MCU. That was the original plan for Avengers 5 when it was the Kang Dynasty before the Johnathon Majors incident and the rebranding to Doomsday.

from my understanding, content on this site's pages are based on what Marvel tells and on what MCU productions reveal.

currently unaware of any contradictions to that scene either from Marvel or in any movie/show.
