With smaller diameters pedal strike in turns can be a real issue. Even 1/2-3/4" reduction in radius (1-1.5" diameter) can be enough to cause issues - it brings the pedals that much closer to the ground when banking turns.
I agree. I have been using BikeInsights.com to compare frame geometry and do try to account for different tire sizes using the "align on ground" view. I know that I am fine with my old stolen 56cm Co-Motion Americano and overall enjoyed the ride. When reviewing other bikes, I try to look at the differences and think what that could affect/effect (hate that word!). I know for instance that if I go from drop to flat bars (something I am not against), then the reach can be a little longer if I plan to use swept back bars, a la Jones H-Bar loop.
I do keep an eye on the ground to pedal spindle clearance just for the reason you wrote about.
