> There's no world where Rust is more unsafe than C though so it's all academic
I think Rust is more unsafe than C due to supply chain issues in the Rust ecosystem, which have not fully materialized yet. Rust certainly has an advantage in terms of memory safety, but I do not believe it is nearly as big as people like to believe compared to a C project that actually cares about memory safety and applies modern tooling to address safety. There seems to be a lot of confirmation bias. I also believe Rust is much safer for average coders doing average projects by being much safer by default.

This is such an incredibly cheap shot. First, the supply chain issues referenced have nothing to do with Rust, the language, itself. Second, Rust's build system, cargo, may have these issues, but cargo's web fetch features simply aren't used by the Linux kernel.
So -- we can have a debate about which is a better a world to live in, one with or without cargo, but it really has nothing to do with the Linux kernel security.
