Nah it wont hurt but it also wont stop me thinking how funny it is to see all those wankers who take their diesels less than 10ks down to the shops and park them in the car park and walk away while they are still running because they are on turbo timers.
They might have their place but I would suggest a large portion of people who have them rarely need them, if you really needed it for hot footing down the street or even distances of a few hundred ks manufacturers would have been forced to put them on, but manufacturers know most of us barely stress the engines we have even if we go bush every other weekend.
