Oh no 1ce, not yet. I actually suggest a force //removenear 10 enderchest whenever one is placed in a creative world (or a simpler solution I'm not seeing).
Disable the placement of the Item ID. Essentials is powerful, and so is Worldguard. If one fails, the other won't.
Work around: worldedit them in. Get banned.
Not to mention, for those who have seen my personal server, they know I have the ability to remove entire block ID's from a world. And I will run that on hoenn, sinnoh, and unova when they are done.
