True. However, keep in mind that this was true for the main ESSID
"ripemtg" this year too: People with devices that didn't support 5GHz
had to connect to the secondary ESSID.

I think we could very well do the same with IPv4 as with 2.4GHz; take
away backwards compatibility for both 2.4GHz and IPv4 on the main
"ripemtg" ESSID, but keep a "ripemtg-legacy" or something like that
available for devices that requires the presence of either 2.4GHz and/or
IPv4.

We wouldn't be the first conference to do so, either:
