Let's not be pedantic. From the wikipedia link: "Loitering munitions fit in the niche between cruise missiles and unmanned combat aerial vehicles (UCAVs) sharing characteristics with both. They differ from cruise missiles in that they are designed to loiter for a relatively long time around the target area, and from UCAVs in that a loitering munition is intended to be expended in an attack and has a built-in warhead."
No Cruise Missiles are not used for observations.
Hence the name of Loitering Munition as suicide drone or kamikaze drone, but there are similarity's, but with a shift of the focus.

But you could say the same about Rockets, some Missiles have them, but also Space-rockets and even Aircraft's or Drones (shorter starts or landings)
