Think of it this way, a system evolving around an AWACS plane is like a computer system evolving around a main frame and client computers while a swarm is like cloud computing. When the AWACS goes out the entire system goes down similar to a mainframe going down while in swarm even if a single server goes down there is only minor effect to the entire system.
The F-22 is functionally an AWACs as is the F-35, precisely foar the reasons you mentioned, the F-35 will bring unprecedented situational awareness particularly with the HMS system, ACC commander Mike Hostage has "dictated" that every training mission will "fail" some aspect of that system?
