I agree with the original poster that once you call someone on foot faulting, you will destroy their service rhythm. Beware though that you could end up ruining your own!
Haven't though about it from that angle, but if it happens to me, I will accept it. The skill to avoid a FF is a skill by itself, just like a forehand.
