Destroy tag: missing API method?

Is it just me, or does the API lack a method to delete tags? You can certainly do it through the GUI. And the tag controller definitely has a destroy method here.

The request to list tags is GET /projects/:id/repository/tags. And the request to create a tag is POST /projects/:id/repository/tags with the content of the tag including tag_name, ref and optionally a message. I'm missing the DELETE request.

Is this intentional? Or is this just missing from the API by mistake?
