Allows to go to sculpt mode, do brush strokes, get out of sculpt mode and have deformation preserved. The issues currently is that the current implementation of CCG storage is created from the limit surface, without displacement taken into account. It is trivial to get displaced coordinates, but it is more tricky to get displaced normals. This is something to be solved next. Another limitation is that this only works for sculpting at a maximal multires level. There is code to be done to support propagation of displacement onto a higher levels.
