Exactly my first thought. I'm thinking that 65,000ft isn't the kind of safety guarantee that I'd want for reliable intelligence, but in the context of getting more bang for buck, I suppose it's more than good enough for situations where a JSTAR would be expensive and overkill.
As a zerg surveillance system where we want to be able to quickly field a lot of cheap capability in places where we don't worry about them getting shot down or don't care if they are, I'm all for it. Just as long as they don't spend a lot of time integrating the system into tactics etc and kill a bunch of people by relying on it in situations where the zerg-airborne-command-and-Hindenburg style mission is just going to leave people blind.
Funny I guess you can compare them to zerg overlords in almost every way. Slow, good detection, cheap, expendable, and painfully obvious targets whenever they do get targeted. Over reliance is the only potential issue I see. Should use them as a powerful backup and be prepared to lose them for odd reasons. A convenience at best.
