I'm..thinking more in that it's supposed to go into Multiverse. If it's a matter of post-production, Disney has said that any projects that are in that area of development, that they won't be as effective. I would argue, they could bump it up just because they didn't properly finish filming for Falcon and Winter Soldier.
Unless, they split F/WS into two half-seasons, with the first half releasing in the Summer and then the second half releasing later in early 2021.
