I think your idea shows good creative thought, but I'm opposed to it. 
First, I like the fact that in the common case the list of network 
interfaces does not need to be configured for either protocol. It's too 
easy to make mistakes, and particularly for new installs this is a great 
feature.

Second, the common way we have to enable or disable things with rc.d, 
including other networking features, is with the _enable variable. I 
think it's reasonable to return ipv6 to being consistent with this.
