Spell Interruption Via Button Press

While I personally find spellcast interruption by moving to be an interesting addition, and something to make us consider our actions a bit differently, I am curious of something. I find it extremely annoying that by double pressing my hotkey, it causes the spell that I am casting to cancel itself. Now, it is to my understanding that eventually, animation lock will not be so bad, and it will be easier to move and cancel shorter cooldowned spells. (I am having some issue with lag causing me to still cast my spell, even when I try to move to stop it) What I am curious about though, is if this double tapping of the spell hotkey will eventually be removed. Mixed with the move-interruption, it is rather bothersome.
