I don't think it does really beg the question: the existence of other
options reduces the impetus for someone to write it and get it
accepted in to the codebase.

And hidden in there is the direct answer to your question:  the
feature doesn't exist because no one has written it.

Perhaps, but most of the time "supersede" (or "prepend" or "append")
will solve their problems fine.  At least, that's my experience from
watching this list.
