Naw, VERY loud warning horn. Each wing tank flows into a feeder tank (12 gallons if I recall?) and has an on/off valve to balance them. If your manage to turn both of them off with power to the airplane you get a loud horn, as a PT-6 burning 400 lbs/hour goes through the feeder tank pretty quick. And like I mentioned earlier, restarting a turbine is a complete different animal.
It's really not an ego contest. It's more like common sense if you think about it.

Switch tanks, then look at the selector. Works good, last long time. If the engine has a hiccup, look at the fuel selector. Been there done that. Guess what, I lived.

Adding some collection of microswitches and indicators is just something else that can break, and on the Navajo is entirely unnecessary.
