What failure modes? IP routing will be as deterministic (ahem) as it is now. E2E session continuity is at risk, but session continuity in the face of massive routing changes is not, as far as I know, a goal in NAT66. The only truly difficult scenario is the one Fred Baker described where traffic could yoyo back and forth. I could see using routing headers.
