I checked the draft documentation for 4.2.3, and here is the list of what is planned.
As usual -- please remember this is an Intention not a commitment, and subject to change between now and the release.
regards,

While I understand the frustration of tiem that could be used otherwise. depending of what you are plannig with script wrapping I would recommend you seriously take a look to the REST API

I had a bit of a run-in with a gpfs developer at a conference once when I complained about how command output changes frequently, breaking customer scripts. He was confused why we weren?t
using `-Y`, and didn?t believe me that it?s simply not documented anywhere!
`-Y` output is essential for interfacing programmatically with GPFS, and I don?t understand why it?s not mentioned in any of the guides or manpages. (Though apparently, according to this thead, it?s since appeared in some newer manpages.)

Just looking/scanning the latest (4.2.2) Spectrum Scale Command (and Programming) Reference I only found a few commands that officially are documented as supporting a -Y option: mmnfs, mmsmb, mmuserauth.
But as many of you have discovered, -Y is accepted and yields "interesting" output for many of the mmXXXX commands.
Moreover the output *seems to* have easily discernible patterns that can be parsed by simple programs.
I believe there is no guarantee that the exact command output formats will not change from release to release, so, as a practical matter, if you're going to parse command output, you're probably better off parsing the -Y output,
even if that is not officially supported.

I thought the header rows defined what the format of the output was. Its a bit weird as there can be multiple header rows for different content rows ...

Sure; but that only helps if you know the flag even exists.
