Oda turning World Government into buffoons where they put more effort into killing their top scientist than they do in trying to kill Robin or Joy Boy Nika. Vegapunk knowing too much information does not mean it's okay to kill him off. This subplot of WG wanting to kill Vegapunk is just Oda's lazy way of writing where he wants an easy path in making Vegapunk another Strawhat ally. And to make it worse Oda sends fodder CP0 with Seraphim to kill the person who created them, that is some great writing there. While at the same time Kizaru and the other admirals are at home sitting on their asses getting high twiddling their thumbs.
