My take home from this github incident is that one should do IPv6 deployment first, and then treat IPv4 as a subset via mapped IPv4 addresses. (Open)SSH had been using the mapped addresses for ages, and they showed up that way for ages. It has stopped for unknown reasons.
I guess that someone was upset with the way they showed up in the logs... (OpenVPN has extra code to ensure that "we received an IPv4 connection on a dual-stack IPv6 socket" gets logged the same as "IPv4 on IPv4 socket", because that reduces the number of confused users down...)
