No, I don't think so. Kicking the can down the road doesn't help much, the longer you kick it the more people say "Whatever, they'll keep putting this off for at least a decade, let's just drop IPv6 from Linux 3.2 and put it back in Linux 4.0" and then where are you.
IPv6 isn't going to just magically happen if you don't make it happen.
ipv6 will be a lot easier to adopt in 2015 vs 2013 so every year we can claw back makes life easier
