Good question: Nope, same GFI in the house for years and I haven't touched it LOL.
Keep in mind what GFI does: The GFI trips when there is a short from one of the "hot" legs to ground (e.g. drop the toaster in water). Reversing the polarity (e.g. swapping the two "hot" wires) would not trip the GFI at all.
