Because the systems add more gas to the mixture when cold it can cause a washing effect on the interior of the cylinders that can erode them. Because the fuel injectors don't need to run tat mixture as long if your driving as the engine warms up quicker it is Better for the engine. 

That's what engineer friend of my father told me a couple years back.

Interesting and informative; however, I would have to ask your dad's friend what affect cold oil has on an engine. I agree there is no need for a prolonged heating up but best to get those fluids circulating before you take off.
