I wouldn't call it corrosive, it's a solvent. It doesn't change the chemistry of polymers, only that a few are soluble in it. (long term storage containers corroding is actually attributed to ethanol consuming bacteria's acetic acid waste, rather than ethanol itself, water is needed for bacterial presence though)
In actuality, most of the affected areas in the tests have been the valves, nozzles and seals of the fuel system. Hoses are amongst the most resilient current components. I would also note that these tests are simulating continued use. That is, if you use it all the time you are more readily going to see it's effects.
On the motor end of the spectrum, it's a different story. You don't need to use a higher ethanol content fuel often to have highly damaging effects to a motor and exhaust system not designed for it's use.
There is no miracle fuel, just use what your car was designed for.
