Short answer: "don't be silly, too many hard things in the Linux Kernel get correct in Rust"
What they should look into is trying to build eBPF and XDP in Rust. Then you get that compiled language speed and safety in the kernel.
A few quotes:
"I view OpenBMC as on its knees with tears streaming down its face begging for someone to please rewrite me in Rust, because if we're going to have a BMC that's going to hang out a socket over the internet, God forbid, or even over the network, I want that thing to be in Rust."
"That the beauty of Rust is its ability to interoperate, cooperate, with native systems or C-based systems; allow for vistas to open up."
