Vulture didn’t turn on Spider-Man in prison and teases Scorpion.

Maybe you could argue it’s just a teaser, but to me it sets up the return of Vulture and the introduction of Scorpion. Although with everyone forgetting Peter Parker the lie Vulture tells is less impactful.

Also the Sony films do weird nothings with Vulture, but I’m ignoring those.

Mordo, “Too many sorcerers”.

He was killed in a deleted scene in Multiverse of Madness which would have been a little lame.

If they make Strange Academy, maybe there? Although I would expect he’s ok with well trained sorcerers, but maybe not if Strange is teaching them.
