It's safe to leave a diesel running while pumping, because it is much harder to ignite, compared to gasoline.
The reason you aren't supposed to pump while your car is running is the fear of creating a spark and igniting the gasoline. A spark isn't going to ignite diesel.
Gasoline has a Flash point of -40°F.
Diesel has a Flash point of 143°F.
