he literally said he likes rust as a programming language, so no.
also it's not "optional" when it's the de-facto standard in the language. you lock yourself out of the broader tooling ecosystem. no language server, no libraries (because they all use cargo), etc. oftentimes you run into ergonomic problems with a language's module system because it's been hacked together in service of the enormous combo build/dependency management system rather than vice versa. you're running so far against the grain you might as well not use the language.
this kind of passive-aggressive snark whenever someone leverages this very valid criticism is ridiculous
