Well since they are covert, they may well be a problem. The best that the “operator” can do is issue these vague blanket warnings to civilian air traffic.
A secret drone can be just as much a problem in or close to civilian airspace as a private drone on approach to an airport.
The height this thing was reportedly at and the FLs it may have traversed to get there should have a few people thinking.
