The main use case is convenience.
Management tools need to manually check that the type starts with
"child<" and recursively make a new QMP call. That's what e.g libvirt
does:
https://gitlab.com/libvirt/libvirt/-/blob/v9.10.0/src/qemu/qemu_monitor_json.c?ref_type=tags#L7367
Parsing the output of HMP info qom-tree is not an option in that case.
