It's a loooong way off. The beauty of Adobe is getting to move projects from one app to another. Cause of their walled garden ecosystem. Any open source solution is going to have to start off piecemeal since blender, gimp, kedenlive, Libre office, et al primary rely on local storage, and use their own file extensions. Itd be a huge enterprise to get them all on the same page using nostr and cloud storage, But i suppose it is possible.
