The fact that LOG is categorized the same as INFO has led me to
believe that they are morally equivalent -- that the only reason
both exist is that one has entries of interest to system
administrators and the other has interest to clients.

Our shop chooses to log all connections and disconnections. That's
mixed with such as which clients broke their connections without
proper handshaking. I am surprised to hear that any time-critical
alerts would be logged at this level, versus the sort of information
you might want for forensic purposes. Perhaps anything which
shouldn't be categorized as INFO to syslog should have some other
(new?) level. ALERT, maybe? Mapping to ERR?
