I know that it's generally recommended to not leave a metal tank mostly empty for long periods to delay any rusting, but don't know if that's a 1 or 2 year worry, or a 5 - 10 year worry.

I'm not sure about the material, but the Volt's tank is sealed and pressurized to help preserve the gas, so I'm sure that helps avoid problems like rust too.
I don't know if the fact that PLUG1N only keeps a tiny amount of gas in the car bypasses the feature, but the computer will actually run the ICE some if it detects that it's been too long on the same tank. The manual recommends using the tank up within a year of filling it. My personal record is 73 days between fillups. The current tank is at 62 days.
