I love status messages and the new state message system is a step backwards. I have no historical data for troubleshooting purposes. If I create a new revision of an application and deploy it, does it have a higher success rate than a previous revision? No clue.  

Also, I don't like that state messages are removed for deleted deployments. I want to know what deployment ran on what machine, regardless of if the deployment still exists or not. How do I know what was installed on one machine if the deployment is removed?

There are a ton of instances where historical state messages would be very helpful. It'd be amazing if you made them as detailed as the task sequence status messages, but at least keeping historical success/fail would be very help.

When I look at the reporting, I'm of course especially interested in the errors.
If there appears to be a structural problem, then a solution is developed and implemented.
However - unless it's a change in the revision of an application - there is no clear way to distinguish between errors from before and after the change.
