That statement seems a little overly dismissive. I have given my explanation. I want to be ahead of the curve. I don't want Neth to be scrambling to get IPv6 in when IPv4 is limited by over utilization. I want IPv6 to be full featured and fleshed out rather than tacked in just enough to make it usable. That is a valid reason, if not one you choose to accept.
Now is this something that needs to be implemented this very instant? No. Is it something that need to be the top of the list or everything will fall apart? No. Is it something we can or should ignore? No. This is the time to get the ball rolling on IPv6. It is the new standard for network communication and some thought needs to be put into how it will be implemented in Neth.
