I think that is likely a good practice, if your battery is in great shape. If the battery is weak, what you gain in prechamber heating, and glow plug filament temperature, is quickly overwhelmed if the starter turns a bit slowly because the voltage is down slightly.
The successful starting sequence in an older Diesel is a tightly choreographed set of events that must be synergistic - meaning together they accomplish something that is greater than could be anticipated by the evaluation of the effects of each subsystem element evaluated in isolation. This also makes it confusing to diagnose poor starting performance - the systems and subsystems examined in isolation don't seem so bad.
