I don't think it's knee-jerk at all. If certain items (datacrons, crystals, pets) were available through the Legacy once you have done what is needed (example: HK-51) you should be able to spend to open them on your other characters. There is no reason NOT to at this point. Think about it as a "New Game +", you start over, but get the benefits of what you have done before. I don't think that's asking too much.
