This seems like a bit of a non-sequitur; the state of non-sudo-rs projects/libraries says nothing about the state of sudo-rs itself.

Not to mention that I'd imagine a similar statement would probably be true for projects and libraries written in any reasonably popular language.

How is this a counter argument for anything? A more permissive license is not inherently a bad thing. Many C and C++ projects are also abandon or in so-so condition, why you uniquely call out Rust makes little sense. Either sudo-rs fills the void or it doesn't, but it is a counter point to this idea that open source projects have no path of evolution. Just because that path doesn't look like how you want it to doesn't mean it doesn't exist.

Sudo uses the OpenBSD license, while sudo-rs is dual licensed under MIT and Apache 2.0. Both licenses seem equally permissive to me.
