Does that mean that they no longer have a part to play? How do you compensate in terms of what you focus on when you want an entire scene in focus? Shooting stopped down should make the whole scene sharp. Where do you focus?
I can only guess that Canon assumes only advance users use distance scale and therefore, the entry-level EF and EF-S lenses which are presumably (by Canon) used by the lightweights do not need these scales. This way, the production cost and price tags can be lowered. Also this would be a good marketing move as it forces more serious users to upgrade their lenses to gain access to the scale.
That said, with AF lenses, the critical need for a precise scale is not as it used to be in MF days. Therefore, even with the expensive line of lenses, the distances are so vaguely marked which still takes some gussing to get the in-between ranges right. I could be wrong, but I find the EF lenses' AF ring do not rotate as much as it did on FD lenses. While this helps faster AF, makes precise MF more difficult.
Extra markings to guide DOF and IR are also becoming a rarity even on many L lenses. Sometimes it seems Canon provides the marking just for the sake of it. This is a pity.
