I realize the above replies got off the topic of `LOG_LEVELS`, which was your initial question. 

If we don't include LOG_LEVELS, but want to have "level" in logs as a best practice, then the user will need to know the string for log levels. If we include them, we can ensure that only these values will be written (or default to "unknown"), then can search or route logs reliably based on log level.
