@ska @tychotithonus the downside of building a new tool with new semantics and configuration format is that in 20 years' time, it might have gotten sufficient adoption to start being considered as a replacement. Network effects aren't just for fax machines and social networks, after all.

The announcement blog post claimed 1/3 of sudo security bugs have been memory safety, so as long as the rewrite didn't introduce at least that many new bugs elsewhere, it's presumably a net-win.
