The reason why you don't need one is because the lobes on a flat tappet cam are tapered. The lifters have a slight conical shape on them, and this causes the lifter to rotate, it also creates a rearward thrust on the cam when it is running.

You can put a cam button on any hydraulic or solid lifter cam if you wish, but it's not necessary to do so. A roller cam, however is a different story because the lobes are not tapered, and of course, a roller cam will not tolerate any walking back and forth as roller lifters don't do well skidding accross the lobe sideways.
