I have had a quick look, and it does not look too complicated, other than the fact that cairo_pdf() is mutually exclusive with pdf(); and the jpeg/png are new to 2.13 so it is probably just nobody has gotten round to it. (and cairo_pdf() also behaves differently with the onefile option). I guess I am almost saying I might get my hand dirty or help somebody else who wants to. So it is probably best to start some discussion.
It is not hard to write your own device functions, especially in 2.14.0.
See rgl::rgl.Sweave for an example.
