Revving Engine Pre-Engine Shutoff

I did a search and couldn't find a discussion on this topic.

Just thought of this after watching Casino Royale again. I'm talking about the scene when Bond pulls up for brunch in the DBS, parks, revs the engine and then shuts it off.

Anyways,

I've been doing some searches online and the most common answers were:

1. It's completely useless now. It was only used in engines with carbs to make it easier to start next time.

2. If you blip the throttle and turn the engine off with the engine revving, fuel will be cut off the moment ignition is off, clearing the cylinders of fuel and leaving it with fresh air (to prevent any type of...corrosion buildup?)

What's the word on this - and does ANYONE do it.
...just curious.
