Why will a divot dry out in the few seconds between making it and replacing it? Main thing is to tamp it down hard so that it reunites with the soil underneath.
Have you ever played in somewhere like Florida? If you had you would realise that on some courses the divot totally disintegrates and you are told before you go out that you should only put the sand and seed mix into the damaged area. It all depends on the type of grass on the course.
It can take a bit of time to get used to the idea of not replacing divots over there but your playing partners will constantly remind you.
