I agree that NA dual-fuel engines are compromised but not to an unacceptable degree.
I've run several non FFVs for years on E85; it works, I like it, and I'll keep doing it but there are a few caveats.
P.S. It is these caveats- mainly cold starting in low temps and to a far smaller degree WOT power- that cause SAE to have reservations. They have to design to the lowest common denominator- "idiot proof".
E45 (50/50 E10/E85) behaves very much like E10 as far as mpg and cool weather ops.
