shouldn't this be the other way round? check keys which are different,
and have a list of hotpluggable ones, skip if any others are different?
that way if we add another property to the agent it's fail-safe
(defaults to not being hotpluggable) until it is added to the explicit
list.

yes, sure. I'll rework the patch and send a v3 tomorrow.
