"you'll often see this stuff on lightbulb connectors."
GM Ford etc uses "bulb grease." Bulb grease is another kind of grease. Will not run like normal Dielectric.
"but, overall, ANY grease is better than dry"
Maybe... Some grease eats plastic or worse... burns. Dielectric grease like most plastic and doesn't burn. Burn? Think switch etc.
