I'd consider it quite sensible to log an error *and* handle it (e.g. by
retrying). In that case, I wouldn't want it to appear with error-severity
in my log - it might be an error string, but it's not an error condition.
Only after bailing on handling an error should it stand out in an error
log. So I don't really agree with that approach, fine as it is.
Just my 2¢.
