The more I think about it, the more I think this is a bluf to push drone designers to overengineer their devices.
Eagles are not scalable, but it is way simpler to train a handful of them as a proof of concept than to eagle-proof existing designs of drones. And given physical and engineering limits, every countermeasure implemented in a drone will cut into the effective payload that is available for the drone to carry on its actual function.
The eagles were never meant to defeat the drones, but to force their designers to handicap those.
