I never heard of anyone doing this as a recall but I see it is listed. Mostly those clips are put on in the aftermarket when you try to do something with a fuel line and you snap one of the (now brittle) clips. I have found them on junkyard cars, so maybe that explains it.
If you want to do it, have at it. The hole in the floor doesn't require "destroying" your floor. You make a three sided cut and pull up the metal. When you're done, you bend the flap back down. Some folks fiberglass it, others add a metal panel, some just tape it. The NHTSA probably would not like tape. FWIW, the 9-5 of the same vintage came with a bolt on cover and a factory hole. Installing the clip itself is a five minute job.
Dropping the tank isn't bad either. The straps always come lose, even in the rust belt, IME. But, the risk are all those plastic hoses being pulled down and all the clamped hoses being detached and removed. I don't like fooling with that stuff if I don't have too... "leave well enough alone" is my policy.
