Wait, what? From my perspective the whole point of the plugin
interface is that it should be stable, in that at least there's
a good chance that a plugin you built will work against multiple
versions of QEMU, and if it doesn't then it should fail with
a reasonable error message telling you to update. I'm not
sure we should be landing the plugins infrastructure if we
don't have that much stability.
