The movie that I meant to reference was Dr Strange in the Multiverse of Madness. It is officially part of the MCU and includes X-men characters such as Patrick Stewart’s Dr. Charles Xavier. So you can’t tell me with a straight face that X-Men isn’t retroactively part of the MCU now.
I’d say more than just “a few exceptions” these days. The Loki and What If shows take place almost entirely on other earths. And Kevin Feige himself says that Deadpool is officially part of the MCU now.
