You can file them off if you have steel or aluminum dropouts.
I will have to check. My current roadbike is a custom made in 1985, and I KNOW it does not have them
My new roadbike, a Habanero Custom Ti, assembled and waiting for better weather, has a ritchey wcs ud carbon fork and may very well have them, I will take a closer look.
Neither have dork disks, although I bet it would give them a slight aero advantage.
edit: I checked and the new bike's fork DOES have the little tab on each side. The old bike does not.
