I differ in that opinion.  You can fashion a hole for one on the end of the shaft so the blade doesn't leave the hub.

The keyed groove with lock pin on the shaft is more meant for a sheering point when equipment gets over-torqued.  Better to sheer the pin than to bend the shaft out of alignment.

If the lock pin sheers off the cotter pin keeps the blade on the shaft and the blade assembly just free spins.
