Is the Hidden Ball Trick a Rarity?

The hidden ball trick relies on the runner losing track of the ball, but with the pitch clock starting when the pitcher receives the ball, runners can just stay on the base until they see the timer start ticking. Raymond says if it's already endangered, maybe it's just extinct because you can't really just hold on to the ball indefinitely anymore. "You can just use that as a tip off if you're a runner and you see that the pitch clock hasn't started yet"
