 Your main concern is stability? QMP in 0.12 and current are in preview
mode, ie. no stability contract until 0.13.

 We broke it already with a few changes (like capabilities support), so
anyone using QMP in 0.12 will have to update, although I don't think QMP
in 0.12 is that useful.

 Having said that, it's been stable for several weeks now and incompatible
changes have to be coordinated with libvirt.

 So, if you think this is worth the trouble someone could do it.

PS: I remember Anthony saying that he'd put somewhere that QMP is a
    preview version in 0.12. But I did not find anything, will submit
    a patch for stable.
