Not if teams in your area expect you to use it.
Generally speaking, on the second horn, if teams are making a legitimate effort to get on the floor/to the throw-in spot, I'll hold the ball for a few seconds. If they're still huddling with zero effort, I'll look at my partner, whistle, call direction & point, set the ball down, start counting, and prepare for the high-tailing to the ball.
This season, I've only had one game where this was necessary, and my partner and I had to do it FOUR times. (I've never seen that many.) Surprisingly, they all got it in under the five seconds, and at least two were opposite line.
