Yes, I was talking about dissipative braking versus energy storage. However, eddy current braking and reverse thrust are completely different in their use of energy. Eddy current braking is turning kinetic energy of vehicle during braking into dissipative heat. Reverse thrust REQUIRES additional energy from the fuel tank to provide a braking force. It is worse than dissipative braking, and FAR worse than regenerative braking.
Incidently, I guess one could make use of dissipative heat in winter. Energy from brakes could be used to heat your vehicle :-)
