I know it's generally accepted that Wandavision is Marvel's "house of M" adaptation but looking at how things are left for 818's Wanda...
They've already announced a Scarlet Witch solo movie already. Wether 'our' Wanda really killed herself or not, the one she took posession of, at least to the rest of her wolrd looks like she just washed the earths smartest and mightiest heros in cold blood, each representing their own groups. The X-men exist in 818, as do F4 ect...their peoples are gonna want to slide on Wanda and they won't have all the information to confirm that it wasn't really her doing the damage.
There's also the prospect of Mordo still being alive and armed with the time stone seeing as how Thanos was missing quite a few stones when they caught up to him in that reality.
