It's safe and only adds minimal overhead on logging level checks 
as long as debug log isn't enabled.

Note though that writing debug logs consume extra resources, and 
it may be noticeable under high load.  The debug_connection 
directive allows to enable debug logging only for selected ip 
addresses to minimize impact.
