FWIW sudo has been maintained by an OpenBSD developer for a while now but got replaced in the base system by doas. Independent of any concerns about Rust versus C, I don't think it's quite as unreasonable as you're claiming to consider alternatives to sudo given that the OS that maintains it felt that it was flawed enough to be worth writing a replacement for from scratch.
sudo had grown a lot of features and a complicated config syntax over the years, which ended up being confusing and rarely needed in practice. doas is a lot simpler. It wasn't just a rewrite of a flawed utility but a simplification of it.
Regardless of the exact terminology used to describe why it was done, my point is that assuming that people are "lunatics" because they want to replace sudo is not a particularly compelling claim, and that's what the comment I was responding to had said.
