In AWS, an autoscaling group includes health maintenance functionality

What is the thinking about how to get this functionality in OpenStack?
Since OpenStack's OS::Heat::AutoScalingGroup has a more general member
type, what is the thinking about what failure detection means (and how
it would be accomplished, communicated)?
I have not found design discussion of this; have I missed something?
Yes :)

The idea is that Convergence will provide health maintenance for _all_
forms of resources in Heat. Once this is implemented, autoscaling gets
it for free by virtue of that fact that it manages resources using Heat
stacks.
cheers,
