It'll certainly have an effect at my local airport (Palo Alto, a little speck of a runway that you see during the left turn to line up with 28L/R at SFO, but one of the busiest GA airports in the US). At busy times when they have 6 or more aircraft in the pattern they have something 2 movements per minute, and anything which slows things down will make sunny Saturday mornings even more of a nightmare than they already are.
Oh well...
