I've worked with a few ex-OE guys, including my close colleague who used
to the IBM DE running the OE project out of POK. Let me tell you, some
of the stories they have are absolutely fascinating! It's my
understanding that the POSIX certification was mainly pursued to meet
the requirements set by NASA. But here's an interesting twist: NASA
doesn't run a mainframe anymore.

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

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.)"
