You are forgetting, there is no need for the electrical pump to mimic a WEAKNESS of the mechanical pump. Regardless of the pump type there should be a thermostat, which is restricting the flow according to thermal needs.

So it doesn't matter how the flow rate from the pump varies, the thermostat has the only opinion that matters there.
Cooling the engine is not a problem, you are right, the thermostat will take care of that.

What I was addressing is overwelming the mixing pipe and flooding the exhaust manifold because the cylinders are not moving fast enough to expel the water injected by the electric cooling pump.
