By the way: if this is functionality is ever being changed, I would also suggest to add other options, like removing access to personal messages, which are “personal” by definition and not something moderators should ever get access to. Frankly, I wouldn’t mind having that functionality removed altogether. I would feel much better if I could tell my members “there is no easy way to access messages” than to say “It’s actually super easy, but trust me, I am not going to (mis-)use it”.
