Indeed in many cases they are the preferred option, going by the number of failed moderators, and worse stuck one's on pest control/hunting rifles, there's a lot to be said for using a thread that less prone to either failure mode. One smith I know of has to machine off at least one stuck moderator a week, using an anti-seize grease and removal after each outing goes a long way in preventing stuck threads!
