It would still give gasoline engine level engine braking. A B230FT car can bring a 3,000lb trailer down a steep mountain without riding the brakes at 3000+ rpm, something that a stock D24T can't do.
I think in practice a throttle body brake on a D24T would let you control hill descent without riding the brakes with any size trailer the car itself could safely tow, which is basically the point of an exhaust brake.
