I mean, yeah you did lack a bit since my post was pretty much pure speculation. It could be "WandaVision might have a reverse House of M to bring mutants into the MCU" wrong but it could be "Infinity War part 1 probably has Thanos kill half the universe with the Infinity Stones to set up part 2" correct. Just using comic knowledge to make educated guesses that might be the direction they're headed for the MCU. Except the stuff I was being looser with is such a deep cut that if you actually knew what I was on about, it is something that was speculated from episode 1 (and actually earlier if you paid attention to the production/watched the trailer).
And who knows? They could change their mind about stuff that seems to be correct already. After all we had the 10 Rings and Mandarin until we found out we didn't. We had mutants in the Maximoff twins until we learned they weren't technically mutants. Hell, we even had Evan Peters as Quicksilver until we found out it was a meta ploy just to make a boner joke.
