Mark,

100% in agreement with this stance.

Just to echo what Fernando has already stated, you can't completely ignore
IPv4 in the home network especially when you are talking about a
multi-segmented network. For example RFC6204 calls for a separate /64 on
each LAN interface per the L-2 requirement. In IPv4 these interfaces
nearly always operate in bridged mode. Supporting bridged IPv4 and routed
IPv6 on the same physical interface could pose a challenge.

Overall I like the concept of not breaking core IPv4 functionality while
focussing all new functionality to IPv6.
