Probably not a big deal if you don't run hard enough to get it hot... but I've seen turbo failures on these "modern" diesels from owners who don't understand the peculiarities of the system.

You can kill the engine at a red light because the turbo already cooled down (if it was hot in the first place) while you were slowing to the light.

If you are hypermiling, then your turbo probably didn't get too hot to begin with.

If you're constantly flooring it trying to gut the engine, then your turbo will be glowing red, but then you probably don't care about saving fuel anyhow.
