This implies that submitter must have an OMVS segment. Is Default User
or Unique User supported nowadays?

And only for UNIX files.
Feels political: Conway's Law?
I believe the author was a UNIX-oriented developer, perhaps daunted
by the co-requisite for allocation. But that was done for cp(1) and
a few other functions:
https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.bpxa500/usmd.htm
And it was done as a function package, so SIGNAL ON NOTREADY is
not supported.
A programmer might kludge SYSCALL PIPE and cp to get a
streamable file file descriptor file.
I understand that compiled Rexx supports ANSI stream I/O for
Classic data sets but not for UNIX files.
