I needed some of the undocumented features and in particular, "reportstyle" with the CSV output. I've submitted an updated 'Locale.c" file that includes this feature for the non-Windows version, 'help' text. I don't have a way to test the Windows code.
There are other, undocumented features that in spite of the limitations (aka., UDP TOS,) are still very useful. Just I don't submit changes without making sure they work.
Let me know how we should approach this problem of documenting the missing arguments.
I didn't see a 'man' page text. However, under 'doc' I see an index.html file that has the existing arguments described. If that is all that has to be modified, I would be happy to add 'reportstyle' to that file too.
Mostly, I'm interested in making sure the undocumented features are covered as long as I've tested them.
