For better or for worse, one of the huge problems with the way the modern Internet is laid out is that IPv4 + NATs mean that the ISPs cannot readily make their own policies for what's going on inside your house. In a world with IPv6 and no NATs, then things would be better.

I suspect that some large number of home network use router/NAT boxes provided by the ISP and it's perhaps more unusual for people to buy their own, so at least that's some hope.

You could even hypothesize some sort of branding standard for future home routers and ISPs insisting that you've got a "certified" home router with some certain set of features.

Hey, we can dream, right?
