The installer writes out its own /etc/hosts file with the known address of ftplist1 so simply adding an AAAA to the DNS zone won't help. But then, to make it work somewhat nicely for the uncommon case of v6 only without v4 or NAT64, the installer would really need to probe for working v4, working v6, and show an appropriate subset of the mirror list. But what is "working v6" anyway? Even though it's 14 years since the famous HE/Cogent cake, you still can't reach chunks of the internet (including c.root-servers.net) from HE, and other chunks over Cogent. So the definition and testing to detect that is not trivial.
