The conesnsus with those who mattered to make that change was pro-Nix, but I have no idea how you'd go back to containers because by that point builds were declarative and the implementation was spread over abstractions and repositories! So if DevOps decided to quit because another company was using SuperNix2, which I think is a plausible thing if you have a team using a risky technology, then it would have required hiring consultants to do it - I think it would have been a months-long refactor going in blind.
