That's gone now. There is no more U in MCU...it's MCUs...plural, and all that I liked most about it was killed.
I get why they did it...now they can drop what I'm sure was most difficult about holding the MCU together. Now they can just make endless shows and movies, slap the MCU brand on it, call it "canon", and pump out content. It's there golden goose to break into the streaming service world. Quantity over quality, imo.
I understand your perspective and you make valid points, but is it confirmed that the multi-verse is gonna be goin on indefinitely?
i thought its just for this phase of the MCU - business wise, like you said, they get to pump out a lot of properties without the connectivity issues due to multiple timelines
but storywise, i think this is their way of bringing in all the other main characters into the fold without having to over-explain where they were all this time (F4, X-men and their related characters, and potentially bringing back characters/recasting characters)
I wouldn't be surprised if the multiverse gets "closed off" ("fixed" in the storyline) after the Kang phase, once everyone they need is introduced, and everything goes back into one timeline for the next phase of Doom/Galactus etc
