Just as with the sudo-rs reimplementation, a doas-rs rewrite is not going to solve the inherent issues we get with SUID binaries. We are better off implementing better models (see ssh and run0).
Again I did not claim it will solve that issue. I am simply suggesting that doas has an easy to use interface and I prefer it over sudo. Somebody pointed out that doas is not maintained on Linux, so I think it would be great to reqrite it in Rust and keep it maintained.
