Why the snark? wasmtime is a (pretty popular) Rust project which uses a JIT, demonstrating that it's not incompatible with Rust. Obviously a proper VM wouldn't depend on wasmtime, but implement its own JIT and paraphernalia.

This is wrong, demonstrably. There are multiple OS kernels written in Rust (with small amounts of ASM glue, as is required in any kernel project).
