Now what's to be said about Porsche warning against an engine sitting at idle for a few mintues?
Is there some danger that this practice done on a daily basis could lead to problems down the line?
I'm going to check with my service manager and see if he's heard anything on this topic.

Yes, because as I said, by letting it sit for a few minutes, you are prolonging the period in which your Porsche engine operates BELOW it's normal operating temperature. Starting it up, quickly followed by gentle driving is the quickest way to get your motor safely, up to operating temps, which is what you're aiming for.
Every owner's manual I've ever had previously - (all were VWs and Audis), have recommended this method, for fuel economy as well as engine longevity. Had nothing to do with materials either, they were all iron-block motors and ran on mineral oil from the factory.
