Redirecting as much heat as possible heat back into the thermodynamic cycles sounds like trying to get work from one heat reservoir.
My take on water injection, for a diesel, is that it promotes heat transfer from hot to cold by making the cold side colder.
Making the engine hotter is bad for the oil, seals, head gaskets and aluminum parts.
Gasoline engines seem to respond well to anything that can help reduce isentropic throttling losses while at light load cruise. Things such as warm air intake, egr, using a smaller engine and running it harder, regearing the final drive for lower cruise RPMs and maybe some form of steam injection cut down on these losses.
