I never said something is broken. The document is meant to be an iteration over what we have today. More precisely, contains two proposals for moving forward with an unified communication channel. And also there is a proposal for a new feature. I asked for feedback on those two communication methods to adopt one; with the goal to support the newly proposed feature.

The current implementation is not broken for the current use cases (the integration in Hawkular). But that is not the point, and neither did I claim that is broken. It's not about fixing something that is broken but about creating something new. Just one example, a distributed environment with multiple Metrics and Alerts deployments will just not work with what is there today. And that was discussed thoroughly prior to making the document public.
