Actually, it don't think it is.  Finish_maps can be achieved using texture_maps, but
then
you couldn't use layered textures anymore.  And maybe there would be a workaround for
this, but IMHO it really is that: a workaround and not a more versatile solution.
And if it was just a "nice but pretty useless" feature: then why do we have
pigment_maps
and normal_maps, but no finish_maps?  I think you could achieve the effects of a
pigment_map with a (complicated) texture_map, so saying that finish_maps are pretty
useless would be the same as saying pigment_maps are pretty useless, and I don't think
many people would agree.
