I wonder if Benedict Cumberbatchs contract is getting short so they are getting Wong built up to take his place. He is already the Sorcerer Supreme.
It was reported a while back that Marvel no longer keep people under multi-picture contracts, so I think more to the point is Cumberbatch is really expensive. While it's not like the Disney+ shows struggle for budgets, blowing a huge chunk of an effects-heavy show like She-Hulk's budget on a Strange cameo isn't practical.
