Great question — answering as the UphillTech team:
You add +r(Read) and all already have read permissions so no harm there +X(eXecute) adds the executable bit only to directories or to files that already have at least one execute permission set for either user, group, other. All the dirs will have execute on all of those so no harm there. All files do NOT have x set on user, group, or others. So no harm there. Command was harmless so no action needed.
