For the sake of being found when folks are searching for it,
some level of mixing will be needed to illustrate that voxel and
raster volume is meant to be the same.

Remember that we (will) have vector volumes, too, And r.volume is
also there. So technically voxel will be more clear in many places
with respect to volume.
