This is replaced by geometry nodes, where volumes can now be generated from point clouds and meshes with more control, and more efficient rendering as a sparse volume. No backwareds compatibility is provided, as this would be complicated, and probably this feature was not used much in the past few years. This node was supported in Cycles only, not by EEVEE.
