Possibly too expensive to re-tool or redesign flat tappet cams for a new material. I am pretty sure the zinc was in there as an anti-scuff agent because of the dragging of the flat lifters, and with new cars all having roller cams maybe they are trying to phase out flat tappets?
Good question for the cam manufacturers.
