I think the consensus we had in the past BoFs and discussion in and around this topic can be summed up as stating that homenet deliverables will:

- coexist with (existing) IPv4 protocols, devices, applications, etc.
- operate in a (future) IPv6-only home network in the absence of IPv4
- be IP-agnostic whenever possible

In other words, anything we do for the IPv6 homenet cannot actively break what's already running on IPv4. Also, trying to define what the IPv4 home network should be has long reached a point of diminishing returns given the effort in doing so coupled with our ability to significantly affect what's already deployed. There's still hope we can help direct IPv6, as such that is homenet's primary focus.  However, when we can define something that is needed for IPv6 in a way that is also useful for IPv4 without making significant concessions, we should go ahead and do so.
