Such control surfaces are called flaperons. Nothing new. You find them
on many aircraft, from gliders to military jets. The system does not
rely on fly by wire, e.g. on gliders it's realised mechanically.

Some of DeHavilland Canada's designs have/had them; I know the Twin Otter
does - it's interesting watching them land in the harbour here with the
entire trailing edge of the wing sagging! The Twin Otter is mechanical, of
course.

For real oddness, the F16 supposedly uses its elevators for roll control;
they can move together (pitch) or differentially (roll).
