It was 1995.
I remember because I was particularly enthused about the advent of
"OpenEdition" on MVS and on VM.
It was ironic, and a bit of a hoot, that other Unix systems (e.g.,
Slolaris, HPUX, even AIX) did not have the same certification.
There were two problems. First, USS was kinda slow for some things, and
a bit fragile when configuring and building many FLOSS applications.
Also EBCDIC. The POSIX spec didn't (or didn't clearly) address the
character set issue. I know that the problem has gotten "better", but
it's still a thing. I eventually backed off my own demand that "OE"
speak ASCII. The fact that newline was consistent and reliably
identifiable in both charsets was enough. But nobody really leveraged it
(newline as an A/E indicator) to the extent we should have.
In spite of the caveats, USS was (is) an excellent implementation.
OpenVM too!

FSF and Linux can reasonably be ignored in this discussion but was there a time
when Unix System Services (of z/OS or OS/390) was competitor to other platforms
that claimed to be UNIX? How many third party apps were available / supported /
marketed for USS as against AIX, HPUX or Solaris? How many of those were
actually being run on USS? Certificate is fine on the wall but what actually
does the job is more important.

To be contentious: nowadays nobody cares. Indeed, when we talk about
non-Windows distributed system we usually think about Linux. Even POWER
machines are more and more used for Linux workloads, not AIX. And the
Linux is not UNIX certified.
The only use I have found in many years for having z/OS UNIX certified is
so that when someone says they hear that z/OS has a "UNIX emulator" or any
one of many similar bogus claims, I can say "No, z/OS *is* UNIX. And BTW
Linux is *not* UNIX." (Of course the FSF would say, Gnu's Not Unix.)"
