I think I already answered that - having the whole list (single QMP
call) is more efficient than calling multiple times per command we are
interested in.  Also, most other query-* commands do NOT filter; having
the 'option' argument introduces filtering.  It's up to Luiz whether we
leave it as is, or omit '*option' for now and save filtering for later,
but I'd rather not have mandatory 'option' as then you have to know in
advance which command line options you care about.
