How prevalent is the use of old style names for ions (e.g. ferric, ferrous) outside the classroom

In teaching my preparatory chemistry courses, I'm constantly wondering whether or not I should be having students memorize the "old names" of common multivalent monatomic cations, such as plumbic for lead (IV), plumbous for lead (II), etc. Every year I teach the course, this information seems increasingly outdated, as I find that I'm coming across these less and less in my general reading. To the readers I'd like to pose this question: In your practical experience, particularly in industry or other fields outside chemistry, do you still employ this style of referring to ions and compounds?
