Early on, I remember there being concerns about forcing ethanol in gasoline used in maritime applications on the theory that the water soluble ethanol would draw water in at a higher rate osmotically and cause corrosion in fuel pumps. I don't know if there have been any long term studies on it, though.

Ask anyone who deals with outboard boat engines (particularly 2-stroke ones). Basically all the concerns were confirmed. The manufacturers try and mitigate it with fancy coatings and whatnot but there's only so much you can do.

It is terrible in small engines too and kills a lot of them (chainsaws, lawnmowers, etc.). Watch any small engine repair videos on youtube and about half of them (or more) were killed because of ethanol in the gas.

Yeah. 2 stroke stuff seems to get hit the hardest regardless of environment. On the plus side carburetors are cheaper than ever. The price is being driven down by sheer volume.
