Looks fine.

There's another `object-add` command a few lines higher up which also
still uses `props` and needs to be changed in the same way.

Care to include it in a v2?
It would also be nice to include the cause in the commit message,
something like:

    `props` was deprecated with qemu 5.0 and removed in qemu 6.0.
    The commands are now generally flattened.
