Quite a few stationary jet engines (power generation, etc.) use water injection
to control NOX emissions, and use fine sprays at the compressor inlets to
increase the air mass and hence performance on warmer to hot days. But the
introduction of water is at high loads, and given what I know about these
engines, I think that this would be occuring for an aircraft equivalent load of
"take off thrust", I think it's called.

If the engine is at low loads and water is introduced into the mix then it'd
probably do what our engines were doing when the WI system failed to shut off -
flame out somewhat spectacularly..
