I think Brett's correct here. The way I explain it to my students is that
the customary order in OOP is


element.detach() violates that common understanding, especially since 
detach is not a reflexive verb.

I really see no need for detach() anymore. I think that 
parent.removeContent(child) is all that's necessary; and detach() as 
currently written is just plain confusing. If we absolutely must have 
that bit of syntax sugar, then the name should be changed to a verb 
that does commonly operate on it's subject, like element.breakAway() 
or some such; but I really don't think we need it.

And of course removing detach() totally eliminates the problems of 
clients unintentionally detaching the root element of a document.
