    sessionMode: Log mode changes
    
    Now that console.debug() makes it easy to log message with DEBUG
    priority, we can be a lot more generous with logging without
    spamming logs (by default).
    
    Those turned out useful in figuring out the issue in the next
    commit, so let's keep them.
