Maybe we could make QAPI support generic filtering for all query-* commands. But there's still a cost with making all query-* commands malloc the space for an entire list only to then have a QAPI layer on top of it do filtering before handing back the single element over the wire, compared to passing the filtering down to the query-* implementation to do the filtering in place. > > It was you who suggested a filter command?
