Small Square Baler With Spear On The Plunger

Ok small baler experts. Found a baler with a spear on the plunger. Owner says it's very beneficial for letting the baled hay to breath if baled a little higher on mositure. Thats fine if you have a breeze blowing through your stack.
Any benefit to the spear or all horse pucky?
