With regard to not whistling a shot clock violation if the defense gets immediate clear control:

There would be issues with timing rules. Under NBA rules, a team is only allowed a flat 24 seconds, from the time they get possession, if they commit a shot clock violation. This is especially of importance in late game situations:

Say there's 27.7 when Team A inbounds the ball with a fresh 24. A1 releases a field goal attempt before the buzzer but fails to cause the ball to hit the basket ring. B2 rebounds the ball with clear and immediate possession of the ball with 1.7 left on the clock.

FIBA: Play on as Team B has gotten clear and immediate possession of the ball thus no violation. This ends up not rewarding good defense. Also, under FIBA rules, since there are no live ball timeouts, basically Team B has to throw up a 3/4 shot. Basically, under FIBA rules, we're going to see end of game fouling, rather than the defense attempt to "play it out," with a lot more time left, not unlike NCAA-M.

NBA: Shot clock violation. Officials will reset the clock to 3.7 seconds. And now Team B, being rewarded for their good defense, will also be allowed to call a timeout and advance the ball to the 28' mark with a full 3.7 on the clock.

It's clear that the NBA doesn't want the offense taking more than 24 seconds off the clock (give or take a couple of tenths when they aren't clearly shown on the game clock) if they commit a shot clock violation as officials will correct this at any point in the game.
