Would it make sense to treat glacier:type=rock as preferable to geological=rock_glacier? These two values appear to express the same thing and recommending more established one as preferable makes more sense to me.
See also Rock glaciers retagged as moraines
I created Tag:glacier:type=rock - OpenStreetMap Wiki and Tag:geological=rock_glacier - OpenStreetMap Wiki - second page currently hints that alternative tagging may be preferable but is not marked as deprecated
