The problem than can occur is the FD lever arm can come to rest on the seat tube and still not drop the chain onto the little ring.

It's a common misconception the the tooth spacing is significantly different on 9, 10 or 11 speed cranks, but in reality there is little difference. What is usually different is the amount of shifting ramp material on the rings.
