1. The Java driver does not use class names as logger names (see https://www.mongodb.com/docs/drivers/java/sync/current/fundamentals/logging/#logger-names), to be able to rename classes, especially non-API ones, without affecting application logging. We may want to use a similar approach.
2. We should also decide and document the meaning of each supported logging level. The Java driver does not, unfortunately, do that as of now.

Addressing the source code notes tagged with TODO-HIBERNATE-43 is in scope of this ticket.
