For me, it isn't the turbo or the coolant temp as much as it is the trans temp. I will let the truck run for a couple of minutes to cool everything down and make sure the transmission has a chance to do so. This will also let the turbo spool down, cool off and the same for the coolant. I know it doesn't have to be done, but that is just what I do. Makes me feel beter and that is all that counts.
Would rather be safe then sorry. No one has said letting it cool down for a few minutes does any harm. I'm not in that big of rush.
