Enemies Smite-Clearing 'Groved' Camps?

Edit One of my commenters has informed me that when an enemy steps within a grove, it is broken. I was unaware of this as the Wikia page and all of the gameplay videos I have seen so far do not demonstrate this. If this is the case I can completely agree, this would be sufficient counterplay, and he would not need this to further balance him.

If possible, could someone please verify this for me. A video link would be preferred.

Should enemies be able to smite-clear a jungle camp that has a maturing or matured grove placed on it? (Maybe fully matured only?)

This would mean Ivern has to be a little more cautious about leaving 'groved' camps unattended.

This also gives the enemy a chance to counter jungle him, because right now it is literally impossible for an enemy jungler to smite steal a camp from under him. They may be able to claim the buff, HP, or Mana, but since he does not fight the camps, they will never be low enough health to claim the kill gold and exp without fighting the camp normally.

One clarification, I wouldn't think I need to add, but I want to be sure, just in case. This would not allow enemy champions to instantly clear a camp if the grove has matured, like how Ivern can. They would NEED to use their Smite.

Also, as a possible compromise for balance sake, either way, the gold and/or exp gained from doing this may not be as much as it would be if they fight the camp normally.
