Sounds like that would cause exceptional wear at the throwout bearing and pressure plate fingers.

Some engines cut fuel during "engine braking." After all, there's no need to burn fuel to slow down a vehicle. Gravity and car momentum are what keeps the engine turning.
Still, braking is braking and it's not the fuel mileage at any one moment that counts, but rather the average fuel mileage over the entire trip.
But if you need to brake anyway to keep your speed down, you're better off doing so in gear.

What about a vacuum canister reservoir and vacuum gauge? It would seem cheaper than buying a pump and in most instances the idea is to have enough braking power for an emergency as engine braking can be done with the fuel shut off anyway.
