Excellent point and not often mentioned as a down side of going to larger wheels on a bike not designed for them.
"Toe clip overlap", as it used to be called, is a problem on many standard road frames, particularly smaller ones, and is the reason very small frames often come with 650c wheels instead of 700c. Even normal midsize frames seem to have some these days but it's a problem only on very tight turns like a U-turn in a 2-lane road. Going to larger diameter wheels could make the problem severe enough that not just the rider's toe but the pedal could hit the tire on a tight turn.
