Is it good to take 2 drivers with so different driving styles? If Vettel wants superstable rear and Leclerc doesn't, I think it's good that Vettel will go out, there is no chance for him if Ferrari will build cars for Leclerc's style. Also, does anybody know what about Sainz' style, how does he drive, as Leclerc or Vettel? If he prefers stable rear as Vettel it will end his carreer in Ferrari, available only 1 role - "barrichello".
If Vettel can't find a place for 2021 but still wants to drive in F1, he should to go to rally for 1 year or at least to buy a rally car and drive it. We say here "take a hair of the dog that bit you": Seb should learn how to manage unstable rear end, after rally on dirty or snowy surface it will be so good for him to feel himself better in F1 car.
