Unless resorts are running at 10-20% capacity, I don’t see how they’d open them without giving guests things to do outside of the resort I’m not sure Disney Springs is enough to keep people occupied and avoid overcrowding at the resorts. Pools are busy pretty much all day with 6 parks and Disney Springs open. And if Universal is open on June 1st, Disney would not be too thrilled with people leaving their property to go to Universal every day. Disney already has set WDW up in a way to discourage anyone from needing to leave property so they have you spending money on them your entire stay.
