Yeah it kind of does, `insertBeforeIndex` would be the spontaneous solution. But to me that eludes to it being a function and not an index. https://developer.mozilla.org/en-US/docs/Web/API/Node.insertBefore refers to it as `referenceElement`, which kind of makes sense and points to my function being badly named, `moveChildToBefore` `moveChildBefore` `moveBefore` ... ?

PS. It's also kind of weird that the arguments refers to *elements* but the descriptions refers to *nodes* in that URL.
