They're bad from a game design perspective. Their block stealing ability will either destroy the world if they do it too much, or create obnoxious eyesores like this if they do it too little:
Sure, they should be special. They teleport, they're hard to kill (not dangerous, they just teleport around constantly), and you need to kill *a lot* of them to get to the End world. That's plenty special. Get rid of the stupid block removing crap that up my trees!
*goes and looks for the mod that turns off enderman block moving...*
