I think it depends, eventually less and less IPv4-addresses will be
available and thus we'll get a lot more different situations, where
unbound with it's IPv4-address might be further away from the hosts
that query it, more centralized.

Also what if people just want a simple modern network with just
IPv6-addresses for simple(r) management ?

If you use IPv4, most of the time, you're doing NAT anyway, might as
well (if it works well enough, for you, which it might not for a lot
of people) use NAT-PT or something similair.

I don't know what kind of things will develop.

I did see the project at [0] was/is also partly funded bij NLnet Labs
and it's a patch to Unbound so I thought it might merge eventually.
