You are. Teams just can't put all their men on one side of the ball, thereby increasing their chances of recovery. Likewise, the receiving team can't take out the kicking team players by forming a wedge, thereby making it easier for their man to get the ball.
And guys on the kicking team, have to be lined up on the line, no "ten yards back and get a head of steam going before they pile into the receiving team's wedge.
Should make onside kicks a bit more of a crapshoot who recovers, and make them a bit safer as well.
