[hibernate-dev] Loggers and categories

Wanted to revisit something that's been bothering me ever since we moved to JBoss Logging : the definition of loggers. While I think we have always understood that there are really 2 different audiences for log messages, I think I have come to have a more clear understanding of what that means and its implications. We have log messages intended for usage scenarios and log messages intended for debugging scenarios. To me, the first groups is represented by the JBoss Logging MessageLogger messages. The second group are the things we simply "pass through" to the underlying log backend (trace, debug messages). In both cases we currently use the name of the Class initiating the log message as the "category name". While I think that is absolutely the correct thing to do in the case of that second group, what about the first group? For that first group I wonder if its better to have "logical category names" more like 'org.hibernate.orm.deprecations' and 'org.hibernate.orm.mapping'... The idea being that its easier to switch these grouped categories on/off.
