When prog array is updated with bpftool users often refer to the map via the ID. Unfortunately, that's likely to lead to confusion because prog arrays get flushed when the last user reference is gone. If there is no other reference bpftool will create one, update successfully just to close the map again and have it flushed. Warn about this case in non-JSON mode. If the problem continues causing confusion we can remove the support for referring to a map by ID for prog array update completely. For now it seems like the potential inconvenience to users who know what they're doing outweighs the benefit.
