I think they're telling everyone 24 because the supply seems unpredictable. Then, when they are sure they have some parts, they move people up.
There's a reason why *everyone* gets pushed back to 24, or was 19 before. It's worst case scenario, which has sadly worsened.
EDIT: Yeah, someone in this thread already said the same thing.
