The command will be rejected at QMP dispatch time instead, avoiding reimplementing rejection by blocking the stub commands. This changes the error message for affected commands from {"class": "CommandNotFound", "desc": "Command FOO has been disabled"} to {"class": "CommandNotFound", "desc": "The command FOO has not been found"} This has the additional benefit that the QGA protocol reference now documents what conditions enable use of the command.
