One interesting about luneburg is that Yankeesama mentioned that they used a luneburg lens on the J-20 that was detachable in flight. Guess that it was not as economical as retractable luneburg and was replaced later on.

Also if it was jettisoned during an op, you want a way to return normal radar visibility when returning to base to aid ATC especially when flying through civilian airspace.

how would the us address this issue considering their lunebergs are a groundside modification?

They don't, obviously. They just assume that the decision to fly with/without LL will be made before takeoff. Which is not terribly unreasonable, mind you, just a bit less flexible.
