Re: [magnum] Dropping default Cluster API driver

I actually really like the approach you're bringing up here which is taking a similar approach to how Kubernetes has successfully scaled out the maintenance of it's different integrations, such as how the Cluster API has a dedicated repo for the OpenStack one, another one for AWS, etc. I don't see why Magnum couldn't remain focused on what it does and allow installing the "driver" that the user needs, focusing on the life cycle, API, certs, etc -- same way that the Cluster API does today.
