That might be the case, but I still find it extremely convenient to have a
well-arranged summary listing of the clients using my AP - especially if I can
simply parse it using awk and merge it with other data (like the dnsmasq leases
file). Grabbing that data from syslog isn't that easy, especially if no
persistent syslog storage is in play.
