Prior to IBM introducing OMVS to z/OS, the term USS was used by VTAM as the acronym for Unformatted System Services. Once OMVS was introduced, I do seem to remember a bit of discussion on the use of USS, as VTAM folks used it, and it was starting to be used by the folks pushing for more use of the Unix side of the house.
I'm not as involved in discussions here, as I used to be, so I do not know where things stand from the VTAM and OMVS groups.
