The fuse's job is primarily to protect the wiring from prolonged faults that arent a dead short circuit which is an infinitely high current on paper.
Those faults are quite rare, and the 200% fuses will blow almost as fast in response to a dead short, and the mosfets will most likely fail before the fuse blows in such a scenario.
Still, I'd put in more reasonable fuse if I had them on hand; odds are is unlikely to protect the board any better, but could in theory prevent a fire by overloading the wires if they're not rated for the same as the fuses.
