Yeah... Although that's just the sort of generic development we'd expect anyway: big shuttlebays in big ships with big guns and room for big labs.
...One thing I could see Starfleet doing as a response to the Space Amoeba is the creation of antimatter-laden flying bombs that look a bit like a big submarine flanked by two smaller ones. Not much good against a maneuvering enemy, or an enemy that can fire back, but really the perfect
thing to give indigestion to a giant space mollusk that is interested in your star system in the culinary sense!
