I've only read Dungeon World for now, but I've played a whole lot of Apocalypse World, and in this specific regard I had the impression they don't differ.
So, Adam, I think there's nothing wrong with the other players waiting for you to tell them what are their characters doing in term of moves. That's a feature of Apocalypse World engine based games; specifically, that's how character moves and Mc moves interact with the fiction and with eachother.
When a player says: "Im' going to cut its throat with my sword," as Mc you could answer with a lot of different reactions, depending on the fiction, your preparation and your principles.
For example, it could be hack and slash, if the monster is ready to retaliate; it could be inflict harm on the monster without needing the move, if the monster is not retaliating for whatever reason; it could be defy danger, if the monster is (let's say) invisible, or surrounded by a cloud of dense gas.
Fact is, as Mc you know what the specifics of the situation and of your preparation (including, let's say, monster hidden resources) are, the other players don't. So, if they went: "I totally hack and slash that lich," you could say: "Wait! When you draw your sword from the sheat, the monster turns gas" (maybe the lich's "release a perfected spell"), depending on the fiction, your principles and your preparation. Or you could say: "No need to hack and slash, it's still distracted by the wizard's spell... Just inflict your damage!"
So, wrapping it up: I don't think there's anything wrong with palyer waiting for you call as Mc on their actions. It's the normal flow of the game.
[Obviously, everything I've said could be totally useless if DW and AW were different in this regard, but they didn't seem to be, reading DW's rules.]
