"id" should be suppressed for backwards compatibility for "-machine id=foo".

"qom-type" is not needed indeed.  But it is so ugly that I would suggest 
doing a backwards-incompatible change to the name the default argument 
of -object, from "qom-type" to "type".  Libvirt doesn't use "qom-type", 
and "type" nicely matches the QOM property name:

  $ qemu-system-x86_64 -qmp unix:/tmp/m1,server,nowait -S \
       -object rng-random,id=foo &
  $ ./qom-get -s /tmp/m1 /objects/foo.type
  rng-random
