Certainly I think the QMP protocol command should just
return all the info (I think current best-practice is
to implement new HMP commands as wrappers round an
equivalent QMP command). At that point we get into UI
design questions about whether we should just print
everything for the HMP command output, or have it default
to just-address with an option to print with the attributes.
I don't have a strong opinion there.
