Never seen before

I don't disagree with the idea of 'fine-tuning'. But just like everything else, the devil is in the details. Speaking specifically NFHS and NCAA, the R1 and R2 are assumed to be trained and paid officials. Line judges may or may not be trained and/or paid, so the level of expertise can vary widely and they are not held to the same standard as R1 and R2.

There are times when the line the line judge(s) is vastly more experienced than the R1 or R2 and there are times when the line judge has absolutely no training in volleyball whatsoever. My guess is that the rules-makers limit the line judge responsibilities due to the lack of expected or required training. If all line judges were required to have a certain level of certification then, perhaps their scope of responsibilities could be expanded.
