That's a pretty cynical way to look at it...
Is it? We just got 22 films culminating in not just half but literally every single living being in the universe across countless planets, solar systems, and galaxies being in danger to Thanos' wrath. Character arcs spanning 8-11 years. Something that no film series can ever hope to replicate. I think it's safe to say that as a "super narrative" nothing in any future superhero films, certainly not within Marvel itself, can ever top or match what we just saw play out.
Which means they're just churning out new movies for the fun of it and for the sake of milking additional millions out of the franchise before it's no longer profitable. And that's fine. And like SMFFH I might enjoy some or even all of the new entries. But the MCU will forever be a separate "post-EG" universe from here on out, of that I have no doubt.
