I would think that -Wuninitialized should take over this.
A non-static uninitialized reference member is just a time-bomb for
the majority of the cases.
Also, as finer grained diagnostic control are being introduced, we
should strive for concise notation (we don't want to degenerate to
numerics or some other hierophyphic notation) but we should make sure
command lines don't become terrific (even though we expect people to
move to Makefiles or fancy IDEs).
