I don't think anything in the gue valve drill is superfluous. Signaling your buddy? Not having dangling regs getting caught in the line or maybe even scooter? Purging the reg to see if the leak was actually what you thought it was?
These are all real life things. Doing them slow and smooth makes sense in the beginning. Hell, doing it smooth and correctly matters when something breaks for real, too. Compounding issues because you get sloppy from rushing isn't going to make your situation any better. Saving 10mins of gas doesn't help of you added 20mins of dive time because you lost visibility and are now lost in a cave.
