The article makes a lot of points and all of them are pretty weak and stem entirely from ipv4 being the "established" protocol. In every case if you had an ipv6 config that worked and you wanted to switch to the ipv4 way of doing thing the result would be just plain worse.

DHCP servers like dnsmasq can already serve lan hostnames even for ipv4.
