As far as being use-case specific, you mean the captive portal use-case? (I like to think that within captive portal use-cases, the ICMP concept is actually very use-case agnostic). If so, I see you point... but, this is the Capport WG. Perhaps we are now talking more generally about any 'network prompted portal interaction' ?

I'm talking about "general network information". For me CAPPORT use-case is one use-case for this kind of information. There are others.

CAPPORT doesn't have to just solve its own problems, perhaps it'd be good to try to come up with a slightly more generic solution and send it for review in INT-AREA for instance? I keep mentioning ALTO because I see their use-case as similar as well, but they invented their own discovery mechanism.

Also, the ICMP error we're talking about, is that feature parity with RFC7710? Because I would like to see DHCP options, RA options and ICMP messages all being able to do the same thing. I could even imagine the ICMP unreach message (perhaps very similar in content) be sent to a multicast group on the LAN, completely replacing the RA/DHCP option? Or we could do it using mDNS instead of in RA? Is there even work on feature parity using mDNS instead?
