We used to administer jump balls at both ends of the court at the free throw lines for held balls. That's why part of the definition of when a jump ball ends includes touching the basket or backboard.

4-28-2 The jump ball begins when the ball leaves the official’s hand(s) and ends when the touched ball contacts a non-jumper, an official, the floor, a basket or backboard.

They could probably remove those words now as it is pretty unlikely that a jump ball tip is going to hit the ring or backboard from midcourt.
