Start up and shut down are the areas where turbochargers are most at risk. Most engine wear occurs at start up.
Basically, it's is okay to shut down a hot naturally aspirated engine, but its really bad for a turbocharged motor. To avoid coking of oil on the bearings, it's always been a good idea to let the engine idle for a minute or so. That's always been the best way to shut down a turbocharged engine.
Perhaps bearing technology has improved to the point where it doesn't matter anymore? I doubt it but like you wrote, we'll see.
