AAF done?

Refused to let AAF use practice squad players or any other NFL players. AAF wanted to be a development minor league for players and the union refused to let that happen. Man I really hate unions. Trucking one tried to murder my grandad on 3 separate occasions. https://m.washingtontimes.com/news/2019/mar/27/alliance-american-football-danger-folding-without-/

Well, considering all the NFL connections within the AAF, it seems like any future league would need a much more explicit partnership with the NFL prior to formation. I don't fully understand how the AAF would think they could be an NFL developmental league without NFL permission in the first place.
