The existing patch was written under the assumption that parameters were
only ever bool; but you are proposing allowing non-bool parameters.

That depends on the QMP interface you come up with for expressing
non-bool parameters. This patch series has already been churning for
several months now, which makes it feel a bit late to be changing the
interface to support non-bool parameters, unless we really like the idea
and can afford another delay in getting this series in.
