I think it is the subject matter which has precluded/inhibited this, Morwen. Asked above about recent songs re corporal punishment of children, Joe could only come up with one fairly mild line from a Stan Kelly song. And apart from contexts like old army/navy songs {The Deserter; On Board A Man O'War}, and a few shrew-tamed ballads like Wife Wrapt In Wetherskins/Wee Cooper Of Fife, it isn't too common a traditional subject either. Intro'd into a new song, pace Lord Invader, it might be thought to appear a bit kinky; which might well be what has put singers off giving it mainstream cover.
