Re: [v6ops] Vicious circle [ULA precedence [Thoughts about wider operational input]]

The difference is that NAT44 made things better. NAT66 arguably doesn’t.
Pretty clearly there is a better alternative for the specific pci case
we’ve been discussing.

This doesn’t mean people won’t do nat66 out of habit anyway, but it will
cost extra and add no value, so I don’t see any reason why it would become
and remain a best practice.
