Literally everything about IPv6 is easier and better. IPv4 is already much slower than IPv6, now you're adding another layer of complexity on top of it? That doesn't sound too good. IPv6 is and has been ready to go forever now.
Your example is mostly a non-issue if you have working DNS. Which ... I know is a big assumption in a lot of networks, especially small to medium sized businesses, it seems. I don't know why DNS is such an issue for so many companies, but I can't help but think people would be more positive about ipv6 if we could get internal DNS solved first.
