This is circular logic though, isn't it?

We don't have throwing WS because throwing is not a main source of attack for battles? (Actually I think we were either told or implied at some point within the last few years that it had to do with the way Shuriken and Boomerangs are coded, but I may be wrong)

But throwing isn't a main source of attack for battles because our throwing weapons are weak (the effective delay on them was greatly reduced and I'm still thankful for that, very much so) AND because... we don't have Throwing based Weaponskills. It would work very similarly tactically to NIN/RNG with a gun fighting a 'link' or enemy summoned by a boss rather than being in range, then using the WS from range on the boss. Except, you know... with something Ninjas have A+ skill in.

Please tell me again that it is some technical limitation, I'd hate to think that right now the logic is 'we aren't updating something you don't use (because we don't update it), because you don't use it enough'.
