The 'singlestep' member of StatusInfo has never done what the QMP documentation claims it does. What it actually reports is whether TCG is working in "one guest instruction per translation block" mode. We no longer need this field for the HMP 'info status' command, as we've moved that information to 'info jit'. It seems unlikely that anybody is monitoring the state of this obscure TCG setting via QMP, especially since QMP provides no means for changing the setting. So simply deprecate the field, without providing any replacement. Until we do eventually delete the member, correct the misstatements in the QAPI documentation about it. If we do find that there are users for this, then the most likely way we would provide replacement access to the information would be to put the accelerator QOM object at a well-known path such as /machine/accel, which could then be used with the existing qom-set and qom-get commands.
