I agree that the 8 char node and 44 char limit on DSN names needs
to be expanded. That is going to hit VTOCs and CATALOGs and JCL,
and dynamic allocation....
But there is always z/OS 4.1 (kinda would match with OE, hmmmm).

Not to disagree but a filesystem would’ve been necessary – beyond 8-character
qualifiers and 44 characters overall.

Ok, mayyybe. Though I'd point out that the existence of USS may have made
(probably did make) those other things easier to implement, but that doesn't
mean they were impossible without it.
And your response doesn't really address my question, I don't think?

Trausti Thor Johannsson's response (which is currently at the top there, but might not be
later) includes "[Java] not only made Mainframe computers not die but made them very
useful."
I don't think I've ever seen anyone claim that Java saved IBM Z, nor that it's
a major use case. Yeah, it's there, but even with zIIPs and zAAPs it's not all
THAT common, is it? Or have I just been working with the wrong sort of
customers?
I have said *many* times that z/OS UNIX nee OS/390 USS nee MVS Open Edition saved the
mainframe. Of course, by "mainframe" I meant traditional z/OS mainframe
environments.
Years ago, I met Bill Schoen at an IBM TDM reception in Poughkeepsie and shook
his hand so vigorously that he probably remembers it to this day.
I told him that I credited him, more than any other individual in the world,
with saving the mainframe. If Don Ault had been there, I would have
congratulated him too. That team (I think they were in Kingston at the time)
implemented a fundamentally-crucial difference in capability that has been
leveraged over the years by TCP/IP, Java, z/OSMF, and many other critical
components. And now Kershaw Mehta and his team, standing on the shoulders of
giants, continue that great work by fundamentally improving z/OS UNIX to
support native containers.
