Only thing shocking about this is that it took this long. Any drone capable of carrying a weapon was going to get one. I mean, look at Ukraine right now. Consumer drones with soda bottle improvised explosives and cardboard drones. I can see a future where most warfare is drone vs drone, to see who can hit the other's supply lines / storage first.
The way Russia's turtling with illegal mines, drones are basically one of the only ways to attack without taking massive losses while also moving slowly and being sitting ducks for artillery.
