IIRC, the separate args idea use case was to allow commands like device_del
to have an ID argument and a path argument, right? If so, I think it doesn't
matter anymore as we have agreed on having a device argument which would
accept both, even under QMP, right Markus?
By the way, if you send patches 09/23, 10/23, 15/23, (maybe) 16/23, 21/23
and 22/23 in a different series, I could try pushing them in my next
pull request.
