There have been a lot of improvements to engine-off cooling of turbochargers as well. My STi for example has a small coolant reservoir located above the turbocharger. When the engine is off, heat continues to be exchanged from the turbo to the reservoir via conduction. Turbo timers, even in high performance cars, are pretty much a thing of the past.

When I was in Europe a few years ago we rented a little Fiat diesel thingie. It looked like a tiny minivan. It had a 1.1L turbocharged engine. The turbo was the size of a large coin! It was so small and spun up so fast that its full capacity was available just above idle; if I recall correctly full boost was at 1500 RPMs. I would expect this Ford turbo will be similar. In other words it won't be something you will be able to "stay out of" during acceleration because it will spin up so quickly and easily.
