My original assertion was incomplete, with regard to the rarity of the event negating any perceived need for a rule change. First of all, I would argue that your multiple foul comparison doesn't address the frequency argument, because it's not in the book to prohibit a rare event. It's in the book to fill a logical hole in the rules; otherwise the penalty for two defenders fouling the same shooter would be four free throws.

As for the fan-shaped backboard, this is a relic rule that addresses an eqipment difference that would otherwise create a similar hole in the rules with regard to OOB violations.

This leads to my next point:

Second, I haven't said we shouldn't have a rule due to a low frequency. (A better example of this would be the 10 second rule for free throws.) I will say that the cure for a low frequency event should come with little to no adverse side-effects. The adverse side effect here would be a limitation (even if rare) of the freedom of movement for a defender attempting to block a shot near the rim. The effect on players having to adjust will be much larger than the perceived benefits of solving a problem that doesn't seem to exist.

As for the 10 second rule, the comparison falls apart due to two reasons. There are zero adverse affects from the rule, and it is a problem that would likely manifest itself if the rule were removed. Enterprising coaches would start using free throws as timeouts, instructing their shooters to take their time.

As for the intent of the rules committee, I'll admit to deducing that intent from the very clear wording in the TF rule, stating that if it's a legitimate block attempt it's legal. I'm assuming they have a reason, and that's the simplest one I can think of.

I will add that I wouldn't be against an alteration to the TF rule on this, allowing for the awarding of points if, in the judgment of the official, the rim rattling resulting from the unsportsmanlike smack on the backboard prevents the ball from entering the basket. While I think the TF is enough, I wouldn't have a problem with adding the points.
