I'm saying that it not clear what effect a loop will have on DHCP PD.

I tried to say that without homenet, existing IPv4 networks are fine.

It could be that people quickly manage to remove the link that causes the loop
or that the impact of a loop is not as serious as portrayed.

If the homenet answer to the question 'how does a phone reach a 
disconnected local network' is that the phone has to become the uplink of the 
network, then I can see plenty of people trying to work around that.
