I don't think TypeInfo is the right place for this. You can however

Well... Because I'm not familiar with qom very much, Let me dig more
details about UserCreatable first :-)
But is a better way to do this to add error handling to
object_unparent API and override object_unparent for your device in
question to throw the error? Then your change doesn't have to be
limited to QMP.
... this is also a good choice.
