Anonymous IDs must not be considered stable. If you prefer, we could try
to filter them out for QMP use. Need to check though if there is a good
location to catch them, but the rule is trivial.

I will also happily drop anonymous IDs again once we have converted all
devices to stable QOM full path addressing. But that will simply take
too much time to wait for it I'm afraid.

Theoretically usable, but extremely unhandy. I would not like so see
such an interface exposed to users.
