Well, looking at it from the context of a typical game, it's not game breaking, since a class with Turn Undead could squeeze, at most, three of these feats into their list (12th, 15th, & 18th).
Now if you play way into Epic levels for that to even become a problem, then it might be DMs call wether there should be a limit.
Furthermore, no one in an E6 game could even take the feat what with the skill prerequisite.
