It shouldn't happen regardless. Disney shouldn't have that much power, and its model isn't one size fits all and takes a certain amount of patience I don't think Zaslav has, especially if canceling a finished film was on the agenda.
Honestly, it's going to take someone to think outside the box, but a big shared universe is all anyone is concerned with and that might not be the smartest move.
And, I definitely don't trust Zaslav's judgment if animation is on the line.
