Pretty much so, also new watercooled ones are so much better in this aspect and modern synthetic oils that starting stopping is much more possible than it used to be.
However especially with longer engines like 6 cylinder ones, there is head warping/cracking issues with sudden temperature changes, so that is another thing to keep on eye when starting/stopping diesel.
I think that efficient P&G will not be very possible with such motor, where you get lot of heat variation, also longer head don't like to be pushed hard when not evenly warmed up, but starting stopping at traffic lights is probably not an issue at all.
Love your engine, care and listen it and it will give plenty of economical mileage
