In the case where there *was* a captive portal on a network, and now there is
not, it might be useful to tell clients that life has changed. The client
might prefer to stay on 3G or pick another network rather than try that
portal.
It might also be meaningful to signal no-captive portal to clients which
have previously connected, but will no longer be challenged (ever? until DHCP
lease timeout?). For instance, if I whitelist your laptop MAC address in my
home.
