No, there's no real reason to. We've decided not to try to maintain a
separate external interface for the layer that Xc is handling. So the
functionality of Xc will soon be folding into Xr. When that happens,
the names can change, (but they will only be internal anyway --- so
only one person will have to worry about it).
